After upgrading to Pro Plan yesterday, i can’t upload product picture anymore on my wordpress website. On Free version was everthing normally.
I receive this error during upload a picture:
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.
It’s work fine now after making some changes: Disable Cloudflare Plugin, Image Resizing on Cloudflare, Disabling Automatic Platform Optimization for WordPress.
I am sorry you are experiencing an issue with uploading images to your WordPress.
Nevertheless, I am also using WordPress on a lot of domains, few of them are using Cloudflare Pro plan as same as you, but I haven’t experienced this error so far.
May I suggest looking into one of my previous posts for further troubleshooting:
Disabling all this is not an option to me as far as it works with all of them → why using Pro plan if it does not work? → I still believe there is something to do at the origin host.
Otherwise, some other request being blocked like “wp-cron” or something similar?
If so, you might want to add the server IP address to Firewall → Tools → IP Access Rules with the action “allow” for your domain/website at Cloudflare dashboard.
