Problem uploading and assigning images

I recently changed webhosting, and have found issues with uploading or assigning images.

My diagnostic log:

I've removed some of the identifying information but if anyone can see any potential issue that may be preventing me from doing the aforementioned tasks, I would appreciate it very much.

TIA

P.S. All MySQL permissions are allowed for the user specified in my config.php file, however there are quite a few options I can change in PHP modules, as it is Wholesale hosting
