Just upgraded to 1.18.1 this morning, and osTicket is hanging every time I post. The post saves, but it just spins after clicking the button. I have to refresh the screen to see it saved.

Check your logs (general server logs, webserver error logs, PHP error logs, MySQL/MariaDB error logs, osTicket System Logs, Browser Console logs, etc.) for any related errors.
Cheers.
