This same display glitch was reported once before by a user in the osTicket.com forum. He later claimed that the issue was resolved, although I wasn’t confident that it was because I didn’t do anything to address it. I can’t reproduce it on my end.
If you would consider giving me access to your installation to have a look I sure would appreciate it.
If yes, I will need you to create a temporary agent account (Admin Panel > Agents > Add New Agent) using info@osticketawesome.com. Be sure to give the account full administrative privileges.
