I have tried turning it off. Actually this problem of the admin account in moodle being disabled has gone, so I will reply to the other problem in the other thread. Sorry about the length of the access logs - I will learn next time.
Cheers
It seems a bit odd that Moodle is not recognising your admin account anymore. If you're handy with the database, you could try making sure that the admin user has their mnethostid field set to whatever the localhost id is (look in the mnet_peer table).
Other than that - the fact that you can't sso into Mahara is also worrying, can you check the webserver logs?
