Hi,we closed the office at the beginning of the month and today our ticket system no longer works.Nothing has been done during the office closure, no updates, no access to the system, no new tickets. Nothing.I installed OsTicket at the beginning of 2015 and it is since then that it has run smoothly. The only Mod I've done is Time to tickets during the beginning of 2016. Not being able to access the system, I can't say what version is running, so I'm posting here hoping to be in the right place.I've also searched into the db but I did not find any mention to the release number.The information I can provide are the following:PHP Version 5.4.45-0+deb7u4MySQL 5.5.38 site link: https://www.cloud-up.it/assistenza/scp/Googling the issue, I found that a blank page means a php problem. If that should be case, nothing should be working. I created a file on the file system (php info) and it works, so I guess it is not a php related issue.Any help would be much appreciated.thanks
