Require, require_once, include and include_once not working correctly within hooks.

Hmmm... Pretty sure that is not related. Hooks don't alter the way PHP works.

What worries me is this:

Code:

Message: require_once(1) [function.require-once]

Where does this (1) come from? Normally you see the filename being included here.
