I accidently added Yanc newsletter twice when I first installed mambo. I didn't try to remove the duplicate component. That was a few weeks ago, so today I couldn't remember which newsletter component I installed so I stupidly installed the newest version of Yanc 1.2. I then tried to delete the one of the three, which made all three useless, i.e., their menus still appear on the components list but don't function. So I reininstalled Yanc 1.2, which got it working again, but the problem now is everytime i try to sign in via the administrator login, either as myself or as admin, I'm returned to the admin login. No error messages. I just get the administrator login screen. I can login via the front end and edit content but I can't login from the backend.
I'm running Mambo v1.0.7 and Yanc 1.2 newsletter.
Help, what have I done?
