Not to hijack your post, but I am in the same boat. My guess is our fix will be the same. I logged in as my superuser changed the title and now I can't get logged back in as a superuser. I am using the same account user name and password, but no configuration button! I am on Ubuntu. This is my internal home use wiki.
It says I am part of the admin group, but I have no admin button! Help! :)
I got this image by adding ?do=check to the end of my default URL after I logged in.
