Are you seeing the HTTP error while uploading media in WordPress? This error usually occurs when you are uploading an image or other files to WordPress using the built-in media uploader. In this article, we will show you how to easily fix the HTTP image upload error in WordPress.
What Causes HTTP Error During Media Upload in WordPress?
There are a number of things that could lead to a HTTP error when you are trying to upload files using the WordPress media uploader. Basically, WordPress is unable to figure out the cause and that’s why it displays the generic ‘HTTP error’ message.
The frustrating part is that this error message doesn’t give you any clue as to what may have caused it. This means that you will have to try different solutions to find the cause and fix the error.
That being said, let’s take a look at how to troubleshoot and fix the HTTP error during media upload in WordPress.
1. Make Sure The HTTP Error is Not Temporary
First, you should wait a few minutes and then try uploading your image file again. This error is sometimes caused by unusual traffic and low server resources, which are automatically fixed on most WordPress hosting servers.
If that doesn’t work, then you may want to try uploading a different image file. If the other file uploads successfully, then try saving your original image file to a smaller size and retry uploading.
Lastly, you may want to try saving the file to a different format. For example, change jpeg to png using an image editing software. After that, retry uploading the file.
If all these steps result in the HTTP error, then this means that the error is not caused by a temporary glitch and definitely needs your immediate attention.
2. Increase WordPress Memory Limit
The most common cause of this error is lack of memory available for WordPress to use. To fix this, you need to increase the amount of memory PHP can use on your server.
You can do this by adding the following code to your wp-config.php file.
define( 'WP_MEMORY_LIMIT', '256M' );
This code increases the WordPress memory limit to 256MB, which would be enough to fix any memory limit issues.
3. Change Image Editor Library Used by WordPress
WordPress runs on PHP which uses two modules to handle images. These modules are called GD Library and Imagick. WordPress may use either one of them depending on which one is available.
However, Imagick is known to often run into memory issues causing the http error during image uploads. To fix this, you can make the GD Library your default image editor.
You can do this by simply adding this code to your theme’s functions.php file or a site-specific plugin.
function wpb_image_editor_default_to_gd( $editors ) {
$gd_editor = 'WP_Image_Editor_GD';
$editors = array_diff( $editors, array( $gd_editor ) );
array_unshift( $editors, $gd_editor );
return $editors;
}
add_filter( 'wp_image_editors', 'wpb_image_editor_default_to_gd' );
After adding this code, you can retry uploading files using the media uploader. If this doesn’t solve the issue, then you can remove this code and try other methods described in this article.
4. Using The .htaccess Method
This method allows you to control how Imagick uses server resources. Many shared hosting providers limit Imagick’s ability to use multiple threads for faster image processing. However, this would result in you seeing the http error when uploading images.
An easy fix is be to add the following code in your .htaccess file:
SetEnv MAGICK_THREAD_LIMIT 1
This code simply limits Imagick to use a single thread to process images.

Hi,
I started having this HTTP uploading error for images that are larger than 600x900px . The size in KB doesn’t matter – 100KB or 300KB – they are uploading just fine if they are less then 600×900.
I have tried all the methods you described without success.
Do you think that changing the theme can help?
You would first want to reach out to your hosting provider to ensure you are not running into a safety measure from their end that would cause the error.
Thanks!
I called them before posting my question – they told me to contact WP support. To me, it also looks like they installed something on their server but are not willing to admit it.
I’ll call again.

Tried all the above and no luck. My issue is only mp3 files, I get the http error. Contacted my hosting provider and they could find nothing wrong. Images upload fine. What am I missing?
For MP3 files you may need to increase the memory limit to 512 in case it is due to how large the files are
Number 3 worked for me! Thank-you so much, that was so frustrating before. You’re site is always so helpful

Also just check the name of your image you want to upload.
Make it simple as this has done the trick for me on multiple occasions.

@Yoeri – Thank you, for me it was just the image name as you suggested, I simplified the name, (it had spaces)
can cloudflare cause this problem?????????????
While possible, it is not likely the root of the problem.

None of these worked in my case. Mod security was the cause. I had to temporarily disable mod security on my web server.
Thanks for sharing what worked for you if other users run into this problem. For most users, they will need to reach our to their hosting provider for assistance in editing mod security
#3 WORKED!!!!! THank you so much for your help!! Stupid go daddy…

SOLVED: my pdf files that would not upload into the Word Press media library with HTTP Error had file names with a semi-colon in them. I deleted the semi-colon and it uploaded just fine. Semi-colons are legal characters in Word docs and pdf files, but apparently won’t upload to Word Press for reasons beyond my knowledge. ; ; ; ;
Thanks for sharing that solution for anyone else running into that problem

Please help if possible.

You may want to ensure you didn’t change your homepage settings while troubleshooting and have you removed the code to see if that solved the missing content?

You may want to try disabling your plugins to see if one of your plugins could be slowing the admin area.
