The overlay disappears after I hit save and it looks like the page does a quick refresh. When I go to check whether or not an image was uploaded by trying to update, there's no thumbnail of the file nor does a slider appear on the Home page.
I'll come back once I'm able to CHMOD data and internal_data again (unless that wouldn't have anything to do with this situation). For some reason they went from 777 today to 755 and I'm unable to change them back.
Thanks for being on it, will keep you posted.
