Thank you for writing Ramrajone.
I use Osticket Version 1.6 ST, PHP 5.6, and Cpanel. Obviously once I have upgraded this OSticket with lastest version of 1.15.4, I have changed to PHP version 7.3.
Note:
As I'm been reading some other Inquiries in this forum, it seems that most people that Upgrade, seem to first upgrade the Osticket to a smaller version let say from OsTicket 1.6ST> OsTicket 1.8>OsTicket 1.15.4, IS THIS THE CORRECT WAY OF DOING IT?
