hi,
i currently experience a really strange behavior ot several drupal installs, which I'm not sure if it is related to my hosting provider or the Drupal install.

the setup:
Drupal: 4.6 and 4.7
special modules: search404

the problem:
whenever there is a request for a non-existing page (i.e. http://www.rubyrange.de/doesnotexist ) the website produces a 'Access Denied' error, which rather should be a 'Page not found' error. the strange thing is, this has been working before like it is suppose to. now it only gives this wierd behavior.

the testing:
i tried to see where the problem could be by removing all 'error message' settings in drupals core settings, even tried using a static node. nothing did anything. it just keeps returning 'Access Denied' for pages that cannot be found.
my hosing provider referred my to the .htaccess file, which i can't see anything wrong with.
