How to resolve the HTTP error image upload WordPress?

Overview

Is it true that you are seeing the HTTP error while uploading images in WordPress? This error typically happens when you are uploading an image or other files to WordPress using the built-in image uploader. In this blog, we will tell you the best way to effectively fix the HTTP image upload error in WordPress.

Common causes of HTTP error during image upload in WordPress

Various things could prompt an HTTP error when you are attempting to upload files using the WordPress image uploader. Fundamentally, WordPress can't sort out the cause and that is the reason it shows the generic ‘HTTP error’ message.

The most frustrating part is that WordPress HTTP error image upload doesn’t give you any clue as to what may have caused it. This means that you will have to try your hands on several different solutions to find the cause and fix the error.

WordPress HTTP error image upload

That being said, it is advised to look at how to troubleshoot and fix the WordPress HTTP error image upload during image upload in WordPress.

Ensure the HTTP error is not temporary

To start with, you should stand by a couple of moments and afterward take a stab at uploading your image file once more. This error is in some cases brought about by unusual traffic and low server resources, which are consequently fixed on most WordPress hosting servers.

If that doesn’t work for you, then you may want to try to upload several different image files. If the other file uploads successfully, then you can try saving your original image file to a smaller size and retry uploading.

Last and not least, you may want to try saving the file to a different format. For instance, change jpeg to png using 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 needs your immediate attention.

Increase WordPress memory limit

The most well-known cause of this error is the absence of memory accessible for WordPress to use. To fix this, you want to expand the amount of memory PHP can use on your server.

You can all do this by adding the below-listed code to your wp-config.php file.

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

This code increases the WordPress memory limit to 256MB, which would be to the point of fixing any memory limit issues.

Change image editor library used by WordPress

WordPress runs on PHP which utilizes two modules to deal with images. These modules are known as GD Library and Imagick. WordPress might utilize both of them relying upon which one is accessible.

Be that as it may, Imagick is known to regularly run into memory issues causing the HTTP error during image uploads. To resolve this, you can make the GD Library your default image editor.

You can do all of this by simply adding this code to your theme’s functions.php file or a site-specific plugin.

1. function wpb_image_editor_default_to_gd( $editors ) {

2. $gd_editor = 'WP_Image_Editor_GD';

3. $editors = array_diff( $editors, array( $gd_editor ) );

4. array_unshift( $editors, $gd_editor );

5. return $editors;

6. }

7. add_filter( 'wp_image_editors', 'wpb_image_editor_default_to_gd' );

After adding this code, you can always retry uploading files using the image uploader. If this doesn’t solve this issue, then you can remove this code and try other ways listed in this blog.

Using the .htaccess method

This way enables you to control how Imagick uses server resources. Many shared hosting providers limit Imagick’s capacity to involve numerous threads for rapid image processing. Be that as it may, this would bring about you seeing the HTTP error when uploading images.

A simple fix is to add the following code in your .htaccess file:

1

SetEnv MAGICK_THREAD_LIMIT 1

This code essentially restricts Imagick from using a single thread to process images.

Wrapping up

Summary

Getting the WordPress HTTP error image upload when uploading images to WordPress is not the greatest feeling. However, do not worry because one of these solutions above will fix this error once and for all.
