I've just upgraded from 1.9.12 to 1.10, with an existing database. When I click on "My Tickets", though, it shows all tickets in the system, not just those that are assigned to me. The "User Directory" page is blank, even though we have dozens of users. And when a client tries to create a ticket, the ticket creation form is blank.When I read the ssl_error_log, I see the following error for each of the above issues:PHP Fatal error:  Class name must be a valid object or a string in /var/www/html/include/class.forms.php on line 1018I haven't looked at the code itself, though.Our set up is as follows:APACHE: 2.4.25MySQL: 5.6.27PHP: 5.6.29OS: Amazon LinuxAny help would be greatly appreciated.TIA!ETA: When I performed the upgrade, the gray box that indicates installation progress reported, "An error occurred," but it did not show any details. That wasn't particularly useful.

I would restore the DB to pre-upgrade status and try again.  I have not seen this error before, and all your versions of software look fine.  I spoke to one of the devs about this and he hasn't seen the error either.

I'm afraid that did not help. I also tried upgrading from a fresh replication of our entire 1.9.12 installation, but that also failed.I also tried upgrading via the 1.9.12 -> 1.9.15 -> 1.10 path, but that, too, was unsuccessful. I'm still getting the same error.

5 days later

This issue turned out to be related to some customizations we had made to the 1.9.12 database that we had forgotten about. Duh. We rolled back the changes, performed the upgrade, and now it is running just fine.

Glad to hear it. :)  I'll mark this as resolved and close the thread.Please feel free to start a new thread if you have furhter issues, comments, etc. :)
