Post-processing of the image failed likely because the server is busy or does not have enough resources. Uploading a smaller image may help. Suggested maximum size is 2500 pixels.
Why Am I Getting the Fix the Post-Processing of the Image Failed Error in WordPress?
As you probably know, you get the above error when you try to upload an image in WordPress. In my case, this appeared overnight, and while I know something had to have changed or updated, I couldn’t tell you what it was. The trouble was the image I was uploading was most definitely meeting the sizing criteria listed in the error. It was only 1100px wide. So something else was going on.
It turns out when you get this error it’s because your PHP settings have maxed out.
Now if you’re not technical, don’t let that spook you. It just means that the coding language that runs your website needs more room to operate on the server. Think of it as needing more elbow room to do it’s thing.
Here are the step-by-step instructions on how to use cPanel, the interface that comes with your hosting package, to fix the error.
If you’re not technical you can always just call your hosting company and ask them to “set your PHP settings to their maxes” and that will get you this same result (or shameless plug – you can join my DIY Website Warriors Membership group over on Facebook).
