I have installed this template and i started it offline. I made no adjustment excpet for put my logo in the offline page. I then went to make the site online in the global configuration and i get a white blank web page. I finally got an error to come up the is the error.

Fatal error: Call to a member function loadMenu() on a non-object in /var/www/baseballBBQ/templates/gk_fest/layouts/default.php on line 68

What do you suggest is the problem and what can i do to fix it.

thanks,

this is the code that is on line 67-70.

Code: Select all

<?php
                $this->mainmenu->loadMenu($this->API->get('menu_name','mainmenu'));
                 $this->mainmenu->genMenu($this->API->get('startlevel', 0), $this->API->get('endlevel',-1));
             ?>


It works now..i had in the installation created a mySQLi and not a mySQL. love your templates.
