7 Techniques to Resolve the http Error During Image Upload in WordPress

ChefBlog, IT Events

A prevalent issue with WordPress is the challenge of uploading videos and images to the media library, often seen as an HTTP error message next to the file name you attempted to upload. If you’re here, it’s likely you’re seeking solutions to this problem.

Fortunately, there are several ways to resolve this, which we’ll explore below. But before that, let’s understand why this error occurs in the first place.

What Triggers the WordPress HTTP Error?

This general error surfaces when the technical specifications of your video or image don’t align with those of the WordPress media library. The library was designed to simplify the management of online media for users. Still, it demands strict compliance with its guidelines. Any deviation triggers an error during file upload.

Diagnosing the http error can be challenging due to WordPress’s often vague descriptions of the root causes. The http error doesn’t always provide a clear reason for the abrupt halt in the upload of a photo or video. Possible explanations could include:

  • A file name containing invalid characters
  • An overly large file size
  • An incompatible file format.

Regardless of the cause, there are straightforward solutions available. Let’s delve into these next.

7 Ways to Rectify the WordPress http Error

Solution #1: Purge Your Browser Cache

The simplest solution to the http error in WordPress is to reload the page or purge your browser cache. Issues can emerge both from your side and the server’s side when you upload new files to a server. It’s crucial to eliminate any conflicting cache memory or connection problems.

To accomplish this, navigate to your browser settings and wipe out all browsing history and data. The process may vary depending on the specific page viewer. The screenshot above demonstrates the relevant dialog window for Google Chrome.

Solution #2: Try Using an Alternate Browser

Numerous browsers are available at no cost. It’s probable that switching browsers will not produce the same error. Therefore, if you’re experiencing issues uploading media in one browser, consider using another and check if the problem persists.

Solution #3: Adjust the File Size

WordPress has a limit on the maximum size of files that can be added to the media library. If your image or video file is larger than the permissible range of 2MB to 150MB, this could trigger the http error.

The most effective solution is to resize your media file using compression software like WinRaR or online tools such as tinypng.com. For a quick overview of these tools, refer to Bonus Section #1 below.

There are numerous plugins available that can automatically shrink the size of the media you’re uploading. Navigate to the Plugins section in your WordPress dashboard, and search for terms like “compress pictures.” You’ll find various beneficial tools as shown in this screenshot.

In Bonus Section #2, we have compiled a list of some remarkable WordPress plugins designed to reduce image size.

Solution #4: Modify the File Name

WordPress doesn’t allow renaming of a file post-upload. However, you can rename the original file before re-uploading it. Avoid special characters (#, $, !, ~, *, etc.) that do not comply with the WordPress file naming rules. Stick to letters, numbers, and hyphens if necessary. A name like “happy-file-1.jpg” would suffice.

Solution #5: Pause for Some Time

WordPress might act erratically if you’re executing numerous updates or uploads simultaneously. If the WordPress http error continues, consider pausing and waiting for a bit. The issue could stem from the server side. Pausing gives the server time to clear its cache. Try to upload your images after a pause of about 3-5 minutes and check if it resolves the issue.

Solution #6: Temporarily Disable Plugins

Plugins, often developed by individual creators using open-source software, can enhance your website’s functionality. However, these plugins might not be created by expert companies experienced in resolving cross-platform issues. If the http error persists, consider a temporary deactivation of all plugins on your WordPress site.

Access your admin panel. Navigate to Plugins on the left side. Choose the plugins you wish to disable by marking the appropriate checkboxes. Navigate to the dropdown menu under Plugins at the top of the page and choose the Deactivate option. Press the Apply button. 

This action should eliminate any conflicts potentially disrupting your uploads. If this method is effective, remember to reactivate your plugins once you’ve finished uploading new media.

Solution #7: Reach Out to Your Hosting Provider

If all else fails, it may be worth reaching out to your WordPress hosting provider. The issue could be originating from their end. For instance, they might have initiated an update just as you were attempting to upload an image, causing server response delays.

That’s all there is to it. If you run into the WordPress http error while uploading a file to the media library, don’t worry. Try implementing one of the strategies we’ve outlined above. In most instances, you’ll be able to resolve the issue without seeking external assistance.
