Thanks, good advice. Ok, so it is running the plugin. If I do that,

$blah = implode('', file('blah.html'));
die();

it displays a blank page on normal pages, as well as when you log out. Could the relative referencing of 'blah.html' be disrupted by the url when you logout possibly? Maybe it's trying to do something like .../forums/login.php/blah.html or somesuch?

edit: I've tried '/blah.html' which made it stop displaying everywhere. I thought that it may be relative to the root of the domain when referenced this way and this instance is in /forums, so I also copied blah.html to the documentroot, and it still did not display. Keeping it relative in some way is important because I do want to distribute this plugin when I'm done with it so I'd like to avoid using a full URL, local path to vBulletin, or anything like that which would require customization.

edit #2:

$blah = implode('', file('/home/username/public_html/forums/blah.html'));

Interesting. Same results from doing it this way. It displays on FORUMHOME and the rest, but not on the logout page. This eliminates any sort of problem like what I speculated about, I'm stumped again.
