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

[vbem2]

Back story:

I was messing around with a plugin in my test forum - using the hook location: vBulletin General: init_startup.

My plug-in sucked. It worked a few times, and then I started getting a test forum-wide error (including in the AdminCP) to the effect of "Unable to add cookies, headers have already been sent. "

I went into the test forum database via phpMyAdmin, and deleted my plug-in record from the plugin table. Didn't help - still got the error.

I then did a bit of searching here and learned the "simple" way to disable plugins that break the Admin CP is by adding the line "define('DISABLE_HOOKS',true);" to my config.php file.

I did that, and it let me get back into the Admin CP, where I confirmed my plugin was no longer listed in the Plugin Manager.

However, when I removed the line "define('DISABLE_HOOKS',true);" from config.php, I can still see the plug-in is active.

How can I kill it? Is it somehow cached in memory because of the hook location I used? I'm stumped.

Thanks for any advice.
