I am seeing something strange with an authentication plugin I wrote and which has worked fine until now, even with Moodle 2.9 systems. When I enable the plugin then even if I try to login as a manual user I get a "session expired" message. (And I also get that message if I try to login through my plugin.) As soon as I disable the plugin I have no problem logging in with the local account. What's weird to me is that (1) I have not seen this before when installing my plugin on other Moodle 2.9 systems, and in any event (2) why should it affect users who authenticate with manual authentication?!
Needless to say I have flushed caches, restarted Moodle, rebooted the Linux box, etc etc.
All suggestions welcome.
