Since our upgrade from 3.8 to 3.9.1 I have been unable to add files to the system in various places. For example, adding a SCORM activity - when I try to drag-and-drop the Zip file I see a circle/slash as if it is not a valid file type. When I drop the file to the page, Chrome downloads the file to my downloads folder. I've tried other browsers and get similar behavior. When I try to use file picker to accomplish the same SCORM upload task, the window opens but then I just get the spinning icon. This happens in other areas like trying to modify theme settings - trying to add a .jpg to a theme using file picker or drag-and-drop methods do not work.
I've tried to turn on debugging and this is where I run into a second issue - changes I try to make in Site Administration do not save. Debugging is one example. It is currently set to NONE, when I make any other selection and click Save changes it reverts back to NONE. Similar behavior with modifying theme settings - try to change any setting - check or uncheck a box, it acts as if I am not logged in as admin and rejects the changes. I am, however, able to apply plug-ins - for some reason dragging a zip file to that page works. I can change a theme, but once it is set I can't further configure its settings.
So I am very stuck since I cannot even turn debugging on to see an error message.
Any assistance is greatly appreciated!
