The error occurs with every theme and also if i deactivate all plugins. So the problem seems to be at a more general place.
Usually my idea is to reinstall, but if it should be a more common WP 2.2 Issue this would not help. Anybody else having this or a similar problem and/or the solution.
Thanks a lot!
Thanks a lot moshu. The moment you wrote how it “sounds” i remebered, that I had been to the index.php in the root dirktore to ha a stats scrpt there. That caused the error and now it works again.
Thanks a lot.
