After I have upgraded to 1.14.1 everything looks normal directly after Log-in, but when switching to page 2 or more, no Tickets are shown.
It is possible to open one Ticket from page 1, but when I close it again, no open Tickets are shown any more.
But when switching to "My Tickets", all my Tickets are shown. That is the same with all agents.
Sometimes the Counter shows no numbers at Open Tickets, unanswered Tickets and answered Tickets, sometimes it shows the correct numbers, but no Tickets.
After Log-out and Log-in again, everything is ok as first described with page 1 and 1 Ticket.
OSTicket 1.14.1, PHP7.3 (but tested with lower Versions as well), My-Sql 5.7
