Hi BobRay,
I tried everything you suggested, including the upgrade, but none worked. I tried disabling FURL (under lighttpd), clearing browser cache and core/cache, but without success.
I disabled FURLs because logging into the manager takes over a minute, look at the time stamps:
78.34.169.11 - - [22/Dec/2011:16:13:23 +0100] "POST /manager/ HTTP/1.1" 302 37 "http://coaching-evaluationen.de/manager/" "Mozilla/5.0 (X11; Linux i686; rv:8.0) Gecko/20100101 Firefox/8.0 Iceweasel/8.0"
78.34.169.11 - - [22/Dec/2011:16:14:45 +0100] "GET /manager HTTP/1.1" 200 3607 "http://coaching-evaluationen.de/manager/" "Mozilla/5.0 (X11; Linux i686; rv:8.0) Gecko/20100101 Firefox/8.0 Iceweasel/8.0"
and I thought maybe the problem is connected to that. After logging in the manager is fast (with disabled browser cache all the time), but still super users (two of them) can only edit each super user, but not the "web users".
Password changes of the web users via the login snippet on the web site can be done.
Any clues what I could try now?
Maybe the super users are really missing some access rights, or the web or anonymous users need to be configured another way?
Cheers
