deleted plugin, but it won't go away...

Thanks, Marco. That fixed it.

To avoid the error in the future: can you suggest which hook location I should use? I was simply generating a random number when any page in the forum is loaded. When I echoed the number (to test it) from the hook location "vBulletin General: init_startup", that's what caused the cookies error in the first place. Which tells me that's not a good hook choice (or a good place to echo output for testing).
