The WordPress website has an issue with image uploads. When we attempted to upload any image through the media manager.

It portrayed the error “An error occurred in the upload. please try again later.” We were able to resolve this issue after several attempts.

There could be a few reasons for this error, so you will have to try it again. There are several possible solutions to this problem listed below.

Uploading images in WordPress causes an HTTP error named “an error occurred in the upload please try again later”

HTTP errors indicate that something went wrong during a file upload in WordPress. It usually happens when you try to add an image or other type of file to the media library. The solution to this problem is covered in no particular order in this guide. Let’s begin, without further ado!

1.  Check Permissions

Ensure that the upload folder’s permissions are set to 755. Although it worked in our case, at times the permissions of the ‘upload’ folder may change due to some unexpected changes on the server.

2. The Culprit Plugins

This issue may be caused by one or more of the recently installed plugins on your WordPress website. Our error was caused by a recently installed plugin for image optimization. We were able to upload the image without any problems after deactivating the culprit plugin.

Try searching for an alternative image optimizer plugin if the HTTP error “an error occurred in the upload please try again later” disappears. To troubleshoot the error further, you could contact the plugin developers.

3. Increase the WordPress memory limit

HTTP errors are commonly caused by insufficient memory in WordPress. Other issues can also arise, such as the 503 service unavailable error. You can fix low memory by adding the following line to your wp-config.php file:

define (‘WP_MEMORY_LIMIT’, ‘256M’);

This code increases PHP’s memory limit to 256MB. Before adding it, check the PHP information for your server’s maximum memory limit.

4.  Editing the .htaccess file

A .htaccess file resides in the root folder of your WordPress installation and acts as a gatekeeper for all sorts of things. A number of functions are controlled by it, including where requests go

Add the following code to .htaccess to fix the HTTP error in WordPress:


When you have completed this step, try adding your file again to see if the problem has been resolved. You can test these code snippets if it does not work:

<IfModule mod_security.c>

SecFilterEngine Off

SecFilterScanPOST Off



# Exclude the file upload and WP CRON scripts from authentication

<FilesMatch “(async-upload\.php|wp-cron\.php|xmlrpc\.php)$”>

Satisfy Any

Order allow,deny

Allow from all

Deny from none


You may want to try implementing them individually, saving your changes, and reuploading your media file.

5. Make sure your cache is cleared

Do you still experience the WordPress HTTP error after trying all the solutions listed above? The “error” you see may have been solved a while ago, but it comes from the local cache. Try clearing your browser cache before you decide there is no solution.
