Voyez-vous un message d’erreur de taille de mémoire épuisée dans WordPress ?
C’est l’une des erreurs les plus courantes de WordPress, et vous pouvez facilement la corriger en augmentant la limite de mémoire PHP dans WordPress.
Dans cet article, nous allons vous afficher comment corriger l’erreur WordPress memory exhausted en augmentant la limite de mémoire de PHP.
Qu’est-ce que l’erreur d’épuisement de la mémoire de WordPress ?
L’erreur WordPress memory exhausted est un message que vous pouvez voir si votre site web a du mal à fonctionner.
WordPress utilise PHP, un langage de programmation côté serveur qui nécessite de la mémoire pour fonctionner.
Comme tout autre ordinateur, les serveurs web disposent d’une quantité limitée de mémoire pour faire fonctionner plusieurs applications en même temps. Les fournisseurs d’hébergement WordPress allouent des tailles de mémoire spécifiques à différentes applications, y compris PHP.
Lorsque votre code WordPress nécessite plus de mémoire que la mémoire allouée par défaut, vous verrez apparaître ce message d’erreur :
Erreur fatale : La taille mémoire autorisée de 33554432 octets est épuisée (tentative d’allocation de 2348617 octets) in /home4/xxx/public_html/wp-includes/plugin.php on line xxx
Il se peut que votre site WordPress épuise la mémoire de son serveur si c’est le cas :
- Beaucoup d’images, de vidéos et d’autres types de médias
- Beaucoup d’extensions WordPress inutilisées
- dépasse les ressources de son offre d’hébergeur
Par défaut, WordPress tente automatiquement d’augmenter la limite de mémoire de PHP si elle est inférieure à 64 Mo. Cependant, 64 Mo n’est souvent pas suffisant.
Ceci étant dit, voyons comment augmenter facilement la limite de mémoire de PHP dans WordPress pour éviter l’erreur de mémoire épuisée.
Vous pouvez utiliser les liens rapides ci-dessous pour naviguer dans le didacticiel :
Remarque : certaines de ces méthodes nécessitent que vous modifiiez directement vos fichiers WordPress. Nous vous conseillons de sauvegarder d’abord votre site web afin d’éviter que d’autres erreurs n’apparaissent sur votre site.
Option 1 : modification du fichier wp-config.php
Tout d’abord, vous devez modifier le fichier wp-config.php sur votre site WordPress. Il s’agit de l’un des fichiers principaux de WordPress, situé dans le répertoire racine, généralement nommé public_html.
Vous devrez utiliser un client FTP comme FileZilla ou le gestionnaire de fichiers de votre panneau de contrôle de l’hébergeur.
Ensuite, vous devez coller la ligne suivante dans le fichier wp-config.php juste avant celle qui dit, C'est tout, arrêtez de modifier ! Bon blog.
define( 'WP_MEMORY_LIMIT', '256M' );
Ce code indique à WordPress d’augmenter la limite de mémoire de PHP à 256MB.
Pour plus de détails, consultez notre guide étape par étape sur la façon de trouver et de modifier le fichier wp-config.php.
Une fois que vous avez terminé, vous devez enregistrer vos modifications et téléverser votre fichier wp-config.php sur votre serveur.
Vous pouvez maintenant visiter votre site WordPress, et l’erreur de mémoire épuisée devrait avoir disparu.
Option 2 : Modification du fichier .htaccess
La méthode suivante consiste à modifier le fichier .htaccess. Ce fichier se trouve également dans le dossier racine du site web de WordPress.
Ici, vous devez coller le code suivant avant la ligne qui dit #END WORDPRESS.
php_value memory_limit 256M
Tout comme le code précédent, il indiquera à WordPress d’augmenter la limite de mémoire de PHP à 256MB.p
Après cela, il vous suffit d’enregistrer vos modifications et de téléverser le fichier sur votre serveur web. Vous pouvez maintenant ouvrir à nouveau votre site WordPress pour voir si l’erreur de limite de mémoire a disparu.
Si vous ne trouvez pas le fichier .htaccess, consultez notre guide sur les raisons pour lesquelles le fichier .htaccess peut être manquant et sur la manière de le trouver.
Option 3 : Vérification du fichier php.ini
Si les méthodes ci-dessus ne fonctionnent pas, vous pouvez consulter votre fichier php.ini.
php.ini est un fichier qui contrôle vos paramètres PHP, y compris la version PHP et les scripts PHP. Il ne s’agit pas d’un fichier central de WordPress, car c’est généralement votre hébergeur qui le gère.
Vous pouvez vérifier son code pour connaître la limite d’utilisation de la mémoire de votre PHP. Pour plus de modifications, vous pouvez consulter notre guide sur la façon de trouver et de modifier le fichier php.ini.
Cependant, comme il s’agit d’une méthode avancée, nous vous recommandons de contacter l’équipe d’assistance de votre hébergeur pour voir s’ils peuvent augmenter manuellement la limite de mémoire de WordPress. Dans le cas contraire, cette méthode risque d’entraîner d’autres erreurs.
Pour plus d’informations, vous pouvez consulter notre guide sur la manière de demander une assistance à WordPress.
Option 4 : Mise à niveau de votre hébergement WordPress
Si vous rencontrez constamment l’erreur « Mémoire épuisée », c’est peut-être le signe que votre site web n’est plus adapté à son plan d’hébergement actuel.
Au fur et à mesure que votre site web attire plus de visiteurs et ajoute plus de contenu, il a besoin de plus de ressources pour fonctionner correctement. Passer à un plan avec une allocation de mémoire plus élevée peut être une solution permanente.
Envisagez de mettre à niveau votre hébergement WordPress si :
- Vous avez essayé les solutions précédentes et l’erreur persiste.
- Votre site web a considérablement augmenté en termes de trafic ou de contenu.
- Vous prévoyez d’ajouter des caractéristiques ou des fonctionnalités qui nécessitent davantage de ressources.
Bluehost propose des plans d’hébergement WordPress abordables et fiables qui peuvent s’adapter aux besoins de votre site web. Ils fournissent une plateforme conviviale spécialement optimisée pour WordPress, ce qui facilite la gestion de votre site web.

Comment éviter d’épuiser la mémoire de WordPress
Maintenant que vous avez résolu le problème d’épuisement de la mémoire de WordPress, voici quelques mesures proactives pour éviter qu’il ne se reproduise :
- Désactiver les plugins inutilisés. De nombreux plugins contribuent à l’utilisation de la mémoire. Passez régulièrement en revue les plugins installés et désactivez ceux que vous n’utilisez pas activement afin de libérer de la mémoire pour les tâches essentielles.
- Optimisez les images. Les images de grande taille peuvent être gourmandes en mémoire. Pensez à utiliser un plugin comme EWWW Image Optimizer pour compresser automatiquement les images avant de les télécharger sur votre site.
- Utilisez un plugin de mise en cache. Les plugins de mise en cache stockent les données du site web, réduisant ainsi la nécessité pour WordPress de les régénérer à chaque visite. Cela permet d’améliorer considérablement les performances du site et de réduire l’utilisation de la mémoire.

This Worked for me.
/**This is a test for memory*/
define(‘WP_MEMORY_LIMIT’, ’64M’);
Thank you for this wonderful share.
joey says
Thanks for the great and simple help! This solved my issue !
Thumbs up;)
Lu says
Should the memory limit ever be higher than 64M? Most WP sites i’ve worked on the average page load never exceeds 40-5megs. The reason I ask, is I read that the WP_MEMORY_LIMIT defines the amount of memory WordPress can use per Apache thread. Which means that multiple threads will use more and more, and eventually swap to disk which is never good.
Anybody an expert and can answer this?
WPBeginner Staff says
It seems like WordPress is either unable to create wp-config.php file or the file gets deleted after the install. Use ftp to make sure that there is a wp-config.php file present on your site. If not then try creating one by renaming the wp-config-sample.php file to wp-config.php file. You will need to manually edit the file and provide your database information.

don’t double click it. Either right click and select EDIT or highlight it and look for an EDIT button somewhere (maybe at the top if it’s Godaddy). Good Luck!
LJ LaValle says
I opened the wp-config.php file from my ftp directory.
I was not sure how to completely enter the adjustment – I didn’t know basic coding for php, so I just copied the basic precursors shown for each entry and added as follows:
/**This is a test for memory*/
define(‘WP_MEMORY_LIMIT’, ’64M’);
It worked!
Ali says
how about i change it to 256 m
Doug says
Thank you!!! This fixed a problem I created myself and saved having to pay someone at the hosting company to update the file.

Hi,
I’ve tried to increase the limit to 64mb, and I got this warning until 5 times:
‘WARNING: Job restart due to inactivity for more than 5 minutes.’
The database backup is stopped until 60s%, and the result is below when it tried to upload to Dropbox:
‘ERROR: Uploaded file size and local file size don’t match.’
What’s wrong with it? I’m using Bluehost.
Thanks!
PS: I’m not a technical person, so give explanation in details

Been having a doozy of a time working on my site and I would sacrifice a MacBook at midnight to get my site working, one little line of code and we are back up. Thanks!
Domestic Herald says
THANK YOU so much!!!! This worked like a charm and took me less than a minute to implement.
Jonni says
Thank you so much!!!!
I’m in the middle of a launch and all of a sudden I couldn’t update or create any web pages on the whole site because of a 500 Internal Server Error. (And of course this happened as soon as I discovered the Home page had a big problem.)
Could get no help from support, am not a web developer.
Yet I was STILL able to follow your instructions and Hallelujah! Miracle of Miracles! Everything works now.
All this work driving traffic, getting new people to the site – almost wasted due to server error – but Disaster Averted! you saved the day.
My sincerest gratitude.
Again, can’t thank you enough.

Thanks so much! I was about to bitch to WooThemes that their $129 extension was breaking my site, but it turned out to be a memory issue. Cheers!

Thanks a million! This is so useful, and more people should see this post.
Adrian says
On line 36/37 of wordpress, wp-config.php you must type:
/** Memory Limit */
define(‘WP_MEMORY_LIMIT’, ’64M’);
For me this problem is solve thi way. You can change 64M with what value you want.
Adam Singer says
This comment is sooo key!
You have to add define( ‘WP_MEMORY_LIMIT’, ’64M’ ); just before the unique key and salts are defined, otherwise the change doesn’t take effect. Thanks!!!
omniafausta says
yesssss thanks, I was wondering why it didn’t work for me. It was because so far no one told me WHERE in the wp-config i had to add this line. THANKS!!!
Rosie Taylor says
Thank you for clarifying this step. Now I know why it never just changing the other line for the value didn’t work before. This saved me big time for a client tonight!
Titel says
Hello,
Today I had a problem with wordpress: after I logged appeared « white screen of death ». We went into cpanel and inserted « define (‘WP_MEMORY_LIMIT’, ’64M ‘)’ in wp-config.php and everything went very well.
Thanks a lot WPBeginner.
Hamza Ahmed says
Thanks a lot, i work very hard with every method i found on internet, but i filled , my problem occur during word-press installation i pasted this code in mid and increase its value to 128 mb , now its works fine, thanks a lot again.
Jeff Danforth says
My host provides 64MB, and wants a hefty kicker to increase the php memory limit – so I’m inclined to be « green » and reduce my memory use.
HOW might I determine what plugins or other things to remove to stay under 64MB
A) php memory consumption, e.g. which plugins are being greedy
B) have I got a memory leak issue, e.g. any plugins being nasty
Thank you for this forum, by the way – I am truly a beginner, but excited about WP (grrr, if I can make it jump its hoops right)
Matthew says
This worked for me, thanks for the tip!
Daniel says
Didn’t work for me, but I’m not sure what it means to be « inside the main php tag ». I opened the file in Dreamweaver and did a search. The word « main » doesn’t appear anywhere on the page. So I put the code in line 2, just after the « <php". Tried it at 64 and 128. Thanks.
Editorial Staff says
The main php tag means just insert it like you did. Sometimes this doesn’t work in which case you have to ask your host.

Deepanshu says
Thanks for the help.
But 64M was already default for me and of course it wasn’t sufficient so I changed it to 96M and I think u should mention this as well.
Jan says
Nice but nothing works – use rackspace cloud – tried 32 – 64 – 128 – 256- 512 – 1024Mb MU site i can’t go more up and only in admin i can’t get access after a plugin from wpmudev so guess i have to delete that and try something pro.

worked perfect.. thank you for sharing, tried a few other fixes but all errored out.

Joke van de Fliert says
thanks! for me the provider had to change a setting to increase the memory limit, but that did fix it!
Jennifer Ortiz says
Thanks a million for this! I got the error message right after the WordPress install–I never even had a chance to add a plug-in.:

All seems to be working fine now.
Timothy Jacobs says
I have tried to do this, but it has not solved the problem. I am on 1&1 hosting and I have tried all the changes, but I still get this error whenever uploading a semi-large picture:

@Timothy Jacobs Contact your host. If they refuse to help, then switch.

Tried placing this at the end of the wp-config.php and didnt work.
However, placing it on top right after the <?php tag worked. Hooray!

Worked for me only after placing just after php tag. Thanks a lot !

PatrickTyrus says
this was a great help, but as you noted it could easily be a plugin, or as someone mentioned it could be a memory leak.
And as others have pointed out, there are memory settings for a reason, some hosts will cut your services if you try to circumvent them.
Is there a way to check on what’s eating memory?
I’ll be searching, but this is something that should be listed under related posts, or as a note and link at the end regarding one of the « numerous solutions for it ». Going for the « simplest one » might get you through the day, but is may not be a good long term solution as it may cover up the real problem and delay the inevitable.
Alexis O'Neill says
Worked for me!! I changed my site language to Spanish and I guess that used up the memory. Added the simple line recommended in the post and voilá!! Back in my admin mode. The really helpful part was « Don’t panic! » because my anxiety level was rising fast.
Thanks ever so much.

Thank you for this post… I had a couple of category / archive query pages that were throwing this error after I upgraded to WordPress 3.1. I was just about to re-write the queries until I found your post in a Google search.
You saved me a lot of work and headaches
Kdb says
I ended up having to switch hosting companies because I couldn’t get my current one to increase the memory from 32MB to, well, anything more. Pretty sad. Took a bit of hassle to transfer three WordPress sites (and multiple other sites), but it was worth it. My current host offers 128MB and my sites are working SO much better. I can actually add plug-ins.
Richard says
Hello
I tried the fix by adding the line immediately after the opening >php tag (line 1)
define(‘WP_MEMORY_LIMIT’, ’64M’);
It did not work for me BUT
I placed the line with comments for my own use on (as it happens) line 22 and it worked.
I am testing this procedure on a test WP site using Twentyten 1.2 Theme
/home/par*****/public_html/wp-config.php
Line 22 /** WP memory limit Note it does not work when placed immediately after line 1 */
define(‘WP_MEMORY_LIMIT’, ’64M’);
Chris says
This trick doesn’t work for me ever since WP 3.
what I found worked was to create a PHP.INI file in the wp-admin folder with the line:
memory_limit = 128M
(or whatever you want to make it)
Editorial Staff says
Sounds like a host issue rather than WP 3.0 issue. We still have this trick working on our clients.

This worked for me! Thanks!!!
Create PHP.INI in the wp-admin folder, with the line « memory_limit = 128M; »

Thanks. This worked for me! Nothing else worked until I read your comment. Website host was not overly helpful.

Eyl says
I have done the trick but seems like nothing happened. The error keep showing so can you suggest other solutions?
Editorial Staff says
On some hosts, this trick won’t work. So you have to ask (beg) them to increase the PHP Memory Limit. OR get rid of the plugin which is causing it.

Seth Merrick says
Great article. A brand new plugin that may soon find its way on to this list is Cobalt WP Boost.
Check it out here:
http://frugaltheme.com/about/cobalt-wp-boost-plugin/
It allows blog owners to raise their WordPress Memory Limits with a couple of mouse clicks, as well as showing at-a-glance memory usage information. WordPress keeps its internal memory limit at 32MB, which is fine for a small-time blog; but if you’re trying to add any robust plugins for social networking or ecommerce applications, 32M will not suffice. This problem can only be expected to worsen with the release of 3.0 which, judging from the beta release, will consume a lot more memory itself without upping the 32MB limit.
Chad McCullough says
I just downloaded the plug-in and I’ll give it a try on my test site. Thanks.
W^L+ says
Just remember that if the problem is a memory leak (either in PHP itself or in some library that is used by a plugin), this will merely delay the occurence.
Before you change the memory limits, you should ensure that you’re using the most up-to-date versions of any plugins. Be sure you are running the newest version of WP. If your host offers multiple versions of PHP, be sure you’re using version 5.
Your hosting service may have preset limits on memory usage. If your editing causes you to exceed those limits, your service may be suspended or canceled without warning.
Dunn says
I tried to deactivate the plugins one by one and found out that the Google XML Sitemaps plugin cause problem.
Muhammad Asad says
I would like to try it! Thanks for the trick.
wparena says
I think the better way is to put this limit in wp-setting.php file where this memory limit already described as 32M, just changed that value to 64M.
Chad McCullough says
Thank you, wparena. I’ll try this.
Chad McCullough says
Changing the settings in the wp-settings.php file fixed my 2 week, driving me crazy, issue! Thank you very much!!

Editorial Staff says
Yes, but editing the core files is not the best way. You would have to change that every time you update WordPress. The way we share in this article, will save you time.
Administrateur
Chad McCullough says
I would much rather not modify core files, if possible. Where would I place the line in the wp-config.php file? I’m not sure where the main php table is.
Thanks for the article and the help!
Editorial Staff says
Place it right after the table prefix
Chad McCullough says
That worked. Thanks!
Kate Mag says
Awesome trick. Is that same with PHP memory limit?
Chad McCullough says
I think that this might fix an issue I’ve been having with my site. I just can’t figure out where the main php table is in the wp-confip.php to place the line.
Thanks!
