OSTicket page loading takes time randomly. Sometimes it works on single click but it hangs randomly for a few seconds then loads ultimately. it is random and with random windows regarldless of any page I click on, admin panel/agent panel, tickets, sub queus, dashboard, etc. I am currently using 1.18.2 - and the same behavior was with 1.18 so upgrading version did not resolve the issue. I also tried, increasing machine resources as well, like CPU, RAM but no luck.
