Previously, I had been running OST 1.15.8 with php 7.4.16. On Friday, I had our webmaster to upgrade our site to PHP 8.1, and then I pushed the new code for OST 1.17 to our website. It has not loaded since then. I get a HTTP 500 error. Got the webmaster to look at the logs and he said these two errors keep coming up over and over. I am not able to login, so I cant see the dashboard to know what versions of things are being reported by OSTicket. Any ideas, or does this give enough information to give any helpful advice.
