I posted this in General but haven't gotten a response yet so I'm trying here.
My site started having trouble uploading images, anything over about 100kb would give an "XHR returned response code 500X error when uploading images" error. I've done everything that I could find after searching the issue, host added ImageMagik, updated to 3.8 and installed Pre-resize Image plugin. Nothing helped after each one was tried. The plugin seems to be installed correctly since the admin side looks right and the images upload and show the thumbnail with the new file size, but when you hit "Update" on the listing it takes you to .../index.php and displays a blank page.
I don't know much about PHP so I'm lost now. Any suggestions?
