Hey Friends,
We had to roll the server back by one month to get rid of a nasty and not to catch error in WordPress. An update had shot down the rights system. And the trouble maker was not to catch. The rollback has removed this bug it seems. All updates are applied again, and the page is still as functional as it should be. The page is for now running fine again. Fingers crossed.
The bad side effect is of course that all posts and registrations in this time span are lost. Please register again in case your account is gone. And sorry for the inconvenience.
Reiner
