since about 15 minutes ALL profiles are empty, they only show:

Profile for
Search: All posts by this registered user.
Date Registered: Not available.
Status:
Total Posts:
Current Email:
Homepage:
Occupation:
Location:
Interests:
ICQ Number:

In add, when I want to change my profile now, the system answers "no such user known".

And what is the ICQ Number ?

And can I use the search function "Search: All posts by this registered user", or is this only for the system-operator?.
