The solution to this problem could be setting the permissions. It took me and the admin a day to figure this out, and the answer was way more simple than lines of code.
Here is how he made them finally show:
Permissions--->click "modify" on member group--->check the "enable ads" box
Some of the codes listed around the sites DO work, but only on the custom themes for me. The default theme hated me:p
