Ah, that'll do it. We don't really recommend using 3rd party mods as the code is not verified by the core development team and they always cause issues eventually. Plus you always have to stay behind on osTicket updates until the mod devs update their mods which is not good especially if there are security patches, etc. I mean you can always apply those manually but it's best to stay on top of the core updates via traditional upgrades.
Cheers.
