Vous rencontrez des problèmes de SSL sur votre site WordPress ?
Le passage d’un site WordPress au SSL peut parfois entraîner des problèmes inattendus. Si vous ajoutez un certificat SSL à un site WordPress existant et que vous rencontrez des erreurs, vous êtes au bon endroit.
Dans cet article, nous allons vous afficher comment corriger les problèmes SSL les plus courants sur WordPress.
Qu’est-ce que SSL/HTTPS et pourquoi devriez-vous commencer à l’utiliser dès maintenant ?
SSL est l’abréviation de Secure Sockets Layers, une technologie de chiffrement qui crée une connexion sécurisée entre le navigateur de l’utilisateur et votre serveur d’hébergement WordPress.
Une fois que vous aurez activé le SSL, votre site utilisera HTTPS au lieu de HTTP. Vous verrez également un cadenas à côté de l’adresse de votre site dans le navigateur pour afficher qu’il est sécurisé.
SSL/HTTPS rend plus difficile l’écoute de la connexion par les pirates informatiques. Chaque site compatible SSL/HTTPS reçoit un certificat SSL unique à des fins d’identification.
Si un serveur prétend uniquement être en HTTPS et que son certificat ne correspond pas, la plupart des navigateurs modernes avertissent l’utilisateur qu’il ne doit pas se connecter au site.
Google encourage tous les propriétaires de sites à utiliser le protocole SSL/HTTPS afin de commander la sécurité globale du web.
C’est pourquoi Chrome marque tous les sites sans certificat SSL comme « non sécurisés ».
Le libellé « Non sécurisé » dans la barre d’adresse du navigateur donne une mauvaise impression de votre entreprise à vos clients/clientes. Par ailleurs, vous devez également activer SSL/HTTPS si vous souhaitez créer un magasin en ligne ou utiliser des services de paiement tels que PayPal, Stripe et Authorize.net.
Compte tenu des avantages et des inconvénients, tous les sites WordPress doivent passer à SSL/HTTPS.
Si vous ne l’avez pas encore fait, alors vous pouvez lire notre guide sur la façon de faire passer correctement WordPress de HTTP à HTTPS pour obtenir des instructions étape par étape.
Recommandé : Consultez notre guide sur la façon d’obtenir un certificat SSL gratuit ou achetez un certificat SSL à prix réduit sur Domain.com.
Cependant, vous pouvez rencontrer quelques erreurs WordPress avec votre certificat SSL. Corrigé, examinons quelques-uns des problèmes les plus courants avec SSL/HTTPS dans WordPress et comment les corriger :
1. Corrigé l’erreur NET::ERR_CERT_INVALID
Le message d’erreur NET::ERR_CERT_INVALID apparaît dans Google Chrome. Les autres navigateurs affichent un message légèrement différent, mais il avertit essentiellement les utilisateurs/utilisatrices que leur connexion à votre site n’est pas sécurisée.
Ce message d’erreur SSL indique que le navigateur de l’utilisateur/utilisatrice n’a pas accepté le certificat présenté par le site. Plusieurs raisons peuvent être à l’origine de ce problème :
- Le certificat SSL est émis pour un nom de domaine ou un sous-domaine différent.
- Le certificat a expiré.
- Votre navigateur ne reconnaît pas l’autorité/autrice émettrice du certificat.
Si vous avez acheté un certificat SSL et demandé à votre fournisseur d’hébergement WordPress de l’installer pour vous, vous pouvez le contacter pour qu’il corrige le problème.
Si vous avez installé manuellement le certificat SSL, essayez de le réinstaller ou contactez votre fournisseur de certificat SSL pour obtenir du support.
2. Corriger les erreurs de contenu mixte après le passage à SSL/HTTPS
Les erreurs de contenu mixte sont causées par des sources qui se chargent encore en utilisant le protocole HTTP non sécurisé dans les URL. Il peut s’agir de ressources telles que des images, des scripts ou des feuilles de style.
Si c’est le cas, vous ne verrez pas d’icône de cadenas sécurisé dans la barre d’adresse de votre site.
Il y a deux façons de corriger les erreurs de contenu mixte SSL/HTTPS dans WordPress. Nous allons vous les afficher toutes les deux, puis vous pourrez choisir celle qui vous convient le mieux.
1. Corriger les erreurs de contenu mixte dans WordPress à l’aide d’une extension
Cette méthode est plus facile et est recommandée pour les débutants. Mais elle peut avoir un impact négatif sur les performances de votre WordPress car l’extension tente de corriger les erreurs de contenu mixte en utilisant une technique de mise en mémoire tampon de la sortie.
Toutefois, si vous utilisez une extension de mise en cache, l’impact se fera uniquement sentir lors du chargement de la première page. Les internautes qui reviennent ne remarqueront aucune différence de performance.
Tout d’abord, vous devrez vous assurer que vous disposez d’un certificat SSL. Si vous n’êtes pas sûr d’en avoir un, consultez notre guide sur la façon d’obtenir un certificat SSL gratuit pour votre site WordPress.
Ensuite, il suffit d’installer et d’activer l’extension Really Simple SSL. Pour plus de détails, veuillez consulter notre guide étape par étape sur l ‘installation d’une extension WordPress.
Une fois activé, vous devez visiter la page Réglages » SSL à partir de votre tableau de bord WordPress pour passer en revue les paramètres de l’extension. Really Simple SSL fonctionne dès sa sortie de la boîte et prendra automatiquement soin de vos réglages SSL/HTTPS et corrigera les erreurs de contenu mixte.
Pour en savoir plus, consultez notre examen détaillé de Really Simple SSL.
2. Corriger manuellement les erreurs de contenu mixte dans WordPress
Cette méthode est plus efficace et meilleure pour les performances de votre site. Cependant, elle nécessite un dépannage manuel.
Tout d’abord, vous devez aller dans Réglages » Général et vous assurer que les options » Adresse WordPress » et » Adresse du site » ont des URL HTTPS.
Si vous voyez des URL commençant par « http », vous devez les modifier et les remplacer par « https ». N’oubliez pas de cliquer sur le bouton « Enregistrer les modifications » pour stocker vos réglages.
Ensuite, vous devez trouver les anciennes URL HTTP dans votre base de données WordPress et les remplacer par les nouvelles URL HTTPS.
Vous pouvez facilement le faire en installant et en activant l’extension Better Search Replace. Pour plus de détails, consultez notre guide étape par étape sur l ‘installation d’une extension WordPress.
Une fois activé, vous devez vous rendre sur la page Outils » Better Search Replace. Dans le champ « Rechercher », vous devez ajouter l’URL de votre site avec HTTP. Ensuite, ajoutez l’URL de votre site avec « https » dans le champ « Remplacer ».
L’extension va maintenant mettre à jour les URL dans votre base de données WordPress.
Si vous constatez toujours des erreurs de contenu mixte, l’étape suivante consiste à dépanner les URL dans les fichiers de votre thème et de votre extension WordPress.
À l’aide de l’outil Inspect de votre navigateur, vous devrez localiser les ressources à l’origine des erreurs et prendre note des fichiers du site à partir desquels elles sont chargées.
Si vous avez l’habitude de modifier les fichiers WordPress, vous pouvez accéder à ces fichiers de thème en utilisant le FTP ou le gestionnaire de fichiers de votre hébergeur. Vous devez modifier chaque fichier et remplacer « http » par « https ».
Une autre alternative est de tendre la main au développeur/développeuse du thème et de leur demander de mettre à jour leur thème. Ils devront utiliser les meilleures pratiques de WordPress pour charger les fichiers, ce qui corrigera le problème HTTP/HTTPS.
Il en va de même pour les contenus mixtes chargés par une extension WordPress. Nous ne recommandons pas de modifier les fichiers du plugin vous-même, vous devez donc en informer le développeur/développeur du plugin et demander une mise à jour. En attendant, vous pouvez désactiver le plugin sur votre site ou trouver une extension alternative.
3. Corrigé les erreurs de trop grand nombre de redirections après le passage à SSL/HTTPS
WordPress vous permet d’imposer le protocole SSL/HTTPS pour la zone d’administration en saisissant la ligne suivante dans votre fichier wp-config.php:
define('FORCE_SSL_ADMIN', true);
Toutefois, dans certains cas, ce seul réglage peut provoquer l’erreur« Trop de redirections« .
Pour corriger ce problème, vous devez ajouter le code suivant à votre fichier wp-config.php, juste avant la ligne qui dit ‘That’s all, stop editing ! Bon blog » :
define('FORCE_SSL_ADMIN', true);
// in some setups HTTP_X_FORWARDED_PROTO might contain
// a comma-separated list e.g. http,https
// so check for https existence
if (strpos($_SERVER['HTTP_X_FORWARDED_PROTO'], 'https') !== false)
$_SERVER['HTTPS']='on';
4. Corrigé la redirection HTTP vers HTTPS de WordPress
WordPress ne redirige pas automatiquement les demandes HTTP vers HTTPS à moins que vous ne lui demandiez de le faire. Si vous utilisez une extension comme Really Simple SSL, alors elle s’occupera des redirections. Dans le cas contraire, vous devrez configurer manuellement les redirections.
Pour configurer la redirection HTTP vers HTTPS, vous devez ajouter le code suivant à votre fichier .htaccess:
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{HTTPS} off
RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
</IfModule>

Google may have cached the non-https version of your site, if you’ve submitted your sitemap you can have Google recrawl your site.

Hi,
Thanks for your post. I was able to fix ssl on one of my sites, however, I have another site with the woocommerce plugin and, with these steps, I couldn’t solve the problem.
I tried to deactivate all the plugins and when I deactivate the woocommerce my site works fine.
The problem is « too many redirects » and with this the page does not load.
Can anyone give me some tips on how to solve the redirects issue in the woocommerce plugin?

If you don’t want to wait for the SSL certificate to be active, you would go into your phpMyAdmin and edit your Options table to revert the site url and home url. https://www.wpbeginner.com/beginners-guide/beginners-guide-to-wordpress-database-management-with-phpmyadmin/

Having problems opening my site on firefox and safari. I’ve installed SSL on one of my domains and the had it verified from the godaddy support team. They said that the ssl is installed fine. But my site doesn’t show the padlock on firefox and safari and sometimes it doesn’t even open.

Your browser may have cached the pre SSL address which could be the cause of your issue.

I did all this. Set up my SSL certificate, installed and activated Really Simple, fixed the mixed content errors (or tried to) with Better Search & Replace and SSL Insecure Content Fixer. However, most of my images are still broken or not loading. They don’t even appear in my media library. The console points to the same file causing the problem—but it’s a file that flat-out does not exist. I cannot find this file anywhere, yet somehow it’s the source of all my images being broken.

Hi guys, first of all, thanks for your great job sharing your knowledge with noobs like me
I’ve just done all the SSL certificate stuff for the first time and got something that seems weird.On the browser that I’ve created the WordPress site and done everything, the website displays just fine . The connection appears to be fully secure and green. But when opening on any other browser or machine, it displays like rubbish. Also, here I get a « Your connection to this site is not fully secure ». When using the Inspect tool, I get 6 of those mixed content errors.
Can you cast some light upon my ignorance, please? Thanks a lot!

You may want to ensure you clear all caching for your site and it can take some time for the SSL to fully update

So.. According to #2 I changed the http to https:, so since than error 404 appears when I try to visit the site with http, if I try with https, than it tells me that this is not a secure site, and it gets blocked.

It sounds like your SSL isn’t active for your site, you would likely want to reach out to your hosting provider to ensure the certificate is active.

Are there ways to fix issues like these if you cannot access the WordPress dashboard? Very often, if there is an SSL issue, the web browser will not even let you access the login page. I would assume you should be able to manually replace links in the database without using a plugin.

I have a web site that I installed Real Simple SSL and Better Search and Replace plugins. I activated both, and ran the Better Search and Replace tool. My problem is when I go to login I get the message (The page isn’t redirecting properly An error occurred during a connection)
This is in the most recent version of Firefox and I cleared cookies and cache.
I also tried this in Safari and it said that « Too many redirects occurred This might occur if you open a page that is redirected to open another page which then is redirecterd to open the original page.
What should I change or search for to get the wp-admin login page to work properly?

I don’t have any SSL certificate and did not make any other change…i already made the mistake before i saw your article.
Now i cant access my domain and my website is inaccessbile and showing ERR_SSL_PROTOCOL_ERROR
Please, what’s the solution?
WPBeginner Support says
You would want to go into your database in the options table as one option to set the addresses back: https://www.wpbeginner.com/beginners-guide/beginners-guide-to-wordpress-database-management-with-phpmyadmin/
Or you can add code to to your wp-config file to change the address, the required code can be found in our article here: https://www.wpbeginner.com/wp-tutorials/how-to-fix-wordpress-login-page-refreshing-and-redirecting-issue/
