I am using osTicket version 1.18.1 and whenever I click on a button that doesn't open another page (meaning that a messagebox-like thing shows up) like for example the button "import user", the messagebox is empty and it is not possible to enter anything into it. The only way to get out of that messagebox is by pressing escape.
Has someone already experienced this issue and, if possible, can I have a solution to this?
