Moved from windows to unix today and everything was going very well.
Then had to do upgrade (1.9 (beta 4) to 1.9.2) admin was logged in and upgrade was going well. Admin was logged out by the upgrade a couple of times, but logged in and continued upgrade. Got to a "certain" point (yup, not sure what point that was) and now admin can't login.
BTW I can't tell you how many times this has happened to me in the past and I always forget how to fix it! Now I also can't find the forum post which addresses this problem. My bad memory tells me it was something to do with the combination of being in maintainance mode and the flag setting on admin or possibly having copied over the sessions folder from the old server.
Any help would be very welcome.
Thank you in advance
