I recently changed my PHP version to 8.0 and I've run into an issue with Page Builder Pro's media manager.
When I upload a jpg, the progress bar goes to 100% and hangs, then I get an upload failed message. The uploaded file is there if I browse folders, but not if I go in via the Images shortcut. PDF uploads work as expected.
I've also notice that there is no image thumbnail being created.
I rolled back to PHP 7.4 and the problem is resolved.
I'm using the latest version of SP Page Builder Pro.
Not sure if this is a bug, or whether I just need to enable something in PHP 8.0.
