I'm trying to install an add on for google analytics. In the Read me info, it's telling me to install a piece of code into this file
/includes/templates/[your_template]/common/tpl_main_page.php
(my template is ''classic") I do NOT have this file. Searched throughtout my file manager, seached in Developers tool kit. Other templates that I DON'T use, that are in my directories DO have this file. But my template doesn't.
Any suggestions? Is there a simpler way to install google an?
The add on I'm trying to install is here
