Blank page after login, logout, posting,...

Hello,

I installed Drupal 5 and currently I am developing my own custom theme. Since yesterday there is a weird problem: When I fill out a form, log in or off or simply do something that triggers an action (other than simply surfing the content) I only see a blank page.

The action is performed (e.g. posting a blog entry), but I can't see anything. The received source code is completely empty. Anybody an idea how to proceed?
