This can be helpfull if you created / installed a plugin or product which has broken your forum and you are not able to access the AdminCP anymore.

To disable the plugin/hook system open your config.php which can be found in your forumroot/includes directory

Just below
Code: 
     <?php
enter


Code: 
define('DISABLE_HOOKS', true);
and save the file.

If you would like to enable the plugin/hook system again, either remove the line again or simply comment that line out. To do so, add two forward slashes " / " so it will look like



Code: 
//define('DISABLE_HOOKS', true);
Next time you would like to disable the plugin/hook system again
you simply have to remove those two " / ".

AdminCP -> vBulletin Options -> vBulletin Options -> Plugin/Hook System
