Good afternoon all,I installed osTicket v.1.10.ProblemEverytime I try to use a help or a function that uses a popup, I get a white/empty box on the screen. Below some examples.By using DevTools feature available in Google Chrome, I get the results you can see in the image below: Error 400 (Bad Request) due to ajax.php file.Additional technical informationIn the image below you can see server information get by osTicket. It seems to be all right, also cgi.fix_pathinfo, that - as I read in other threads of this forum and also of github one - is often the cause of the problem.Field labels are in Italian because I installed it.phar file (that I can confirm since now it is not the cause). I installed osTicket on hosting linux of Register.it (an Italian provider).Php version is 5.6.24, API Php MySql version is 5.5.31, server version is Apache/2.2.14 (Unix).I checked php.ini file and I can confirm that cgi.fix_pathinfo is rightly set as 1.I would be very grateful to anyone who could help me to solve this issue.If further information is needed, please ask me.Thank you in advance.
