Warning problem after moving my opencart shop

Got warning problem after moving my opencart shop admin panel How can i fix this ?

I assume, you tried to create a Shop Subdomain Link, and screwed up,
and this one does NOT belong to your Opencart Software anyway:
http://carbon.opencartstore.com/ads.php
since you could not call an OC-SUB-File directly, out of a Sub,
regardless of it's in this case, PHP-extension.

If your Server Path look's like this:
/home/mantas/www/shop/admin/controller/common/home.php
then, your shop needs to be http-linked, accordingly.

Or then, if called by use of a subdomain, linked/forwarded correctly, and declared/defined
in the corresponding .htaccess, to make it work.
