He just told you....

Also this error is from a plugin you've installed. You need to disable each of your plugins then turn one at a time to see which one is causing this.

If you cannot log into the Admin CP then to disable the plugin system, edit config.php and add this line right under <?php

define('DISABLE_HOOKS', true);

This will disable all hooks and allow you to log in properly with no hooks running.
