My cart is currently installed under my root directory (routineisforrobots.com) and is working fine. I want to move it to a sub-folder (routineisforrobots.com/shop) instead as I am not currently running my shop and need my root directory for other things.

I have followed this tutorial to the letter and am still having problems:

My admin login is working but the actual shop page comes up with this error:

Fatal error: Cannot instantiate non-existent class: notifier in /homepages/14/d128477381/htdocs/shop/includes/autoload_func.php on line 79

I never touched that folder and the cart works fine if I upload everything back to the root directory so I don't know what's up.

If anyone can help it would be much appreciated. This is causing me to have a major migraine!
