I'm running Ubuntu 16.04/PHP7/Nginx (YES I know this isn't officially supported)/osTicket 1.10. The software is fairly unusable the way its currently functioning. No matter what I click on with cgi.fix set to 0 or 1 it makes no difference, I receive blank popup windows by trying to update an agents password, when I select delete on a ticket and the confirmation window pops up, even submitting a ticket the thank you window is a blank popup. Basics like configuring settings, forms, etc all work until it gets to a part requiring a popup. I've read many posts about AJAX errors, and more but none related entirely to what I'm experiencing/my configuration. Appreciate any help in advance!
