Hello,
We are on 1.17, and on Nov. 16th I tried to upgrade to 1.17.2. After following the upgrade guide, as I've done with all previous upgrades, it caused a hard crash for the entire site.
Blank page, one sentence:
osTicket\Session\SystemSessionHandler: must implement osTicket\Session\AbstractSessionhandler
That error shows up for the main login page and the /osticket/scp/login.php page.
I can't get around it, and my Google-fu is finding no hits for how to fix that issue.
I also can't find any related errors in the log files.
I extract/restore my 1.17 backup file and everything works again.
I even tried to do an incremental upgrade to 1.17.1, and that upgrade caused the same error message.
On 1.17 we are experiencing the issue where users timeout quickly while creating a new ticket. I've implemented the fix from the following page, but it has not helped.
https://forum.osticket.com/d/101833-users-having-to-double-submit-tickets-through-web-portal/13
https://github.com/osTicket/osTicket/pull/6360
And I changed the agents and users from "session timeouts" of 0 to 20160 minutes, or 2 weeks, and we're still having the new ticket timeout issue. Also cleared cache and cookies on the user's browsers.
Attachments are in the local file system, not in the database.
I may not be able to test any ideas until after November 28th, (vacation mode, limited access to network) but I though it would be beneficial if any others have this issue, to at least get the ideas flowing.
Thank you!
