What changed in XOOPS to bring this fatal error into play?
-----
Some more data: When logging in this morning, it accepted my webmaster name and password and said logging in. I found myself NOT logged in and back at the anonymous user view of the site. I tried twice and then logged in with a test user with normal privileges. That user worked. I logged out and now I can login as webmaster. But I still have the first time admin section loop....
