Beautiful and eye-catching images are a crucial part of almost any website, and when you regularly upload images to your WordPress website, it's natural that you'll run into the occasional error message. One of the most common errors is the “Post-processing of the image failed probably because the server is busy or does not have enough resources” message. This error can be caused by a variety of factors, but luckily there are several solutions you can try to fix it. The first thing you should do is check your server's memory limit. If it's set too low, it won't be able to handle large image files.
To increase the memory limit, you'll need to access your server's php.ini file. From here, all you need to do is set your memory_limit line to the maximum in the drop-down menu; in my case, this was 512M. It saves when you select it, so don't worry about having to hit the “Save” or “Confirm” button anywhere. If you're using a caching plugin on your WordPress site, it's also possible that the cached version of your site is preventing images from being uploaded properly. To fix this, you'll need to clear your cache.
If you're not sure how to clear the cache for your specific tool, the plugin's settings menu is usually a good place to start. You can also check the official developer documentation for more information. Strict reliance on cloud-based data solutions can have unintended consequences and is never 100% risk-free. We review recent news about accidental deletion of data by Adobe. Another solution is to try uploading smaller images. Suggested maximum size is 2500 pixels.
This will reduce the amount of resources needed to process the image and should help prevent the error from occurring. If you're uploading very large image files and need more server resources, consider moving to a more advanced hosting platform with more server resources. This will give you more flexibility when it comes to uploading large images. Finally, if all else fails, you can try using a browser uploader instead of the WordPress media library uploader. Unlike the WordPress image uploader, the browser uploader does not support multi-file selection or drag and drop. According to the error message, the image you are trying to upload is probably greater than 2500px, which is the maximum resolution for images that are allowed on your WordPress installation. If you need to link very large image files, you can upload them separately to your website via FTP or another method and link smaller thumbnails you've uploaded to WordPress to the URL where those larger images reside. Every time you add an additional installation on a server with limited resources, you increase your chances of encountering the dreaded “Post Image Processing Failure” issue.
After trying all these other solutions with no luck, I checked the console and got a 500 error in the js load script. I have found that even with this error, refreshing the media page shows them in the library, which means that in the end they load. Next, we'll share five solutions to try the next time the WordPress media library doesn't want to cooperate with your creative vision. WordPress processes every image that is uploaded to it to create smaller versions that can be responsively displayed on smaller devices, such as tablets or mobile phones.Either way, this is my final suggestion on how to fix the failed image post-processing error on WordPress. Remember to also delete your WordPress server and cache (for those who use a WordPress cache plugin).
And since I'm hosting this site on WordPress, and boy if WordPress has a lot of problems, I could also post something about how to solve those cases. Here is a link to the topic that was discussed among core WordPress developers about 7-8 months ago.
