How to fix HTTP image upload errors in WordPress (simple)

Do you need to fix HTTP image upload errors in WordPress?

This error can be particularly frustrating when you create content in WordPress. This usually happens when you upload images or other files to CMS using the built-in WordPress media library.

In this article, we will show you how to easily fix HTTP image upload errors in WordPress.

What is the reason for HTTP errors during WordPress media uploading?

Many things can cause HTTP errors when you try to upload files to a WordPress website using the WordPress media uploader.

Basically, WordPress can't figure out why, which is why it displays a generic "HTTP Error" message.

The frustrating thing about this WordPress HTTP error is that it doesn't give you any clues about what might be causing the error. This means you have to try different solutions to find the cause and fix the error.

That being said, let's see how to troubleshoot and fix HTTP errors during media uploads in WordPress. Feel free to use the link below to jump to a specific method:

• Method 1: Make sure the HTTP error is not temporary
• Method 2: Deactivate all WordPress plugins
• Method 3: Increase WordPress memory limit
• Method 4: Change the image editor library used by WordPress
• Method 5: Use the .htaccess method
• Method 6: Update PHP version

Method 1: Make sure the HTTP error is not temporary

First, you should wait a few minutes before trying to upload the image file to your WordPress website again. This error is sometimes caused by abnormal traffic and insufficient server resources, and most WordPress hosting servers automatically fix these issues.

If this doesn't work, you may want to try one or more of the following:

• Refresh the browser or clear the browser cache.
• Resize the file and rename it, and upload it to the media library again. Check out our list of image optimization plugins to reduce file size.
• Save files in different formats. For example, you can change JPEG to PNG using image editing software. After that, try uploading the file again.

If all these steps still result in an HTTP error, the error is not caused by a temporary failure and you absolutely need immediate attention.

Method 2: Deactivate all WordPress plugins

If you have just recently installed a new WordPress plugin, it may be incompatible with your other plugins and interrupt the image upload process. To see if this is the case, you can disable all WordPress plugins.

If the HTTP error disappears after the WordPress plugin is disabled, then this may be the culprit for the HTTP upload image error. You can install alternative plugins or contact the developer for support.

Method 3: Increase WordPress memory limit

WordPress is written in the PHP programming language. Additionally, the amount of memory allocated to different PHP processes is determined by your web hosting server.

If uploading images requires more PHP memory than available memory, you may see HTTP image upload errors in WordPress.

To resolve this issue, you need to increase the memory that PHP can use on the server.

You first need to access the site's files using the FTP client or the File Manager application in the Web Hosting Dashboard. Next, go to the root directory and find the wp-config.php file.

Then you need to edit the wp-config.php file using a text editor and add the following line of code to it:

 define( 'WP_MEMORY_LIMIT', '256M');

This code increases the WordPress memory limit to 256MB, which is enough to solve any memory limit issues.

Finally, you have to save the file and upload it back to the server.

Method 4: Change the image editor library used by WordPress

WordPress runs on PHP, which uses two modules to process images. These modules are called GD Library and Imagick. WordPress can use one of them, depending on which one is available.

However, Imagick often encounters memory problems, resulting in HTTP errors during image upload. To resolve this issue, you can set the GD library as the default image editor.

You can do this by simply adding this code to the functions.php file of your WordPress theme or using WPCode (recommended):

 functionwpb_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');

For more details, you can see our guide on how to add custom code in WordPress.

After adding this code, you can use the Media Uploader to retry uploading the file. If this doesn't solve the problem, then you can delete this code and try the other methods described in this article.

Method 5: Use the .htaccess method

This method allows you to control how Imagick uses server resources. Many shared hosting providers limit Imagick's ability to use multithreading to speed up image processing. However, this causes you to see an HTTP error when uploading the image.

An easy fix is ​​to add the following code to the .htaccess file:

 SetEnv MAGICK_THREAD_LIMIT 1

This code just limits Imagick to use a single thread to process images.

Method 6: Update PHP version

If your WordPress website is using an outdated version of PHP, an HTTP image upload error may be triggered. This is because newer PHP versions have performance improvements and generally use less memory.

Fortunately, it is easy to check and update the PHP version of the site. For more details, see our beginner's guide to learn how to update your PHP version in WordPress.
