Sleepyk, in your includes dir, there should be a config.php file.
In that file, at the very top, right after the <?php tag, add this :

PHP Code:

$debug=1; 


Once done, save the file and upload it, overwriting the old file.

Next in your admincp, under Vbulletin Options, there should now be the choice to 'add a new setting'. Perform the necessary step(s) as per the hack's instructions.

Once done, you will need to reverse the change you did on the config.php file.
Remove ( or uncomment ) the line you added earlier on and re-upload it again.
