At times, you may run into conflicts caused by add-ons. These conflicts may prevent you from accessing your control panel to disable the offending add-ons.
To fix this, you can disable add-ons via the
library/config.php. Simply add this line of code at the end:
$config['enableListeners'] = false;
This will disable all code that is being run by add-ons. You should then go into the admin control panel and disable the offending add-ons from there. The line you added to library/config.php should then be removed.
