I just recently upgraded from 7.2.? to 7.4.1. Then updated from 7.4.1 to 8.0.2. After updating a few modules (feedback, form and list, media) Everything seems to work except that I noticed that the File Upload in the File Manager does not work. After clicking on the icon to open the File Upload box it shows the spinning circle (like it's loading) but nothing ever happens. Permissions looked okay but I temporarily adjusted them to allow all access by everyone, still no luck. Where do I look next?
