Hi,
I am using J1.6
I installed GAcode 1.2.0, but now nothing works, not the site, nor the admin panel.

I get the following error:
Fatal error: Call to a member function isAdmin() on a non-object in /home/content/36/7472236/html/plugins/system/gacode/gacode.php on line 54

PLEASE help me to get the site back up

Hello,

this plugin was not tested with Joomla 1.6. So you should remove the fiels.
