The full error is:
Blocked a frame with origin "http://deltavmap.com" from accessing a frame with origin "http://googleads.g.doubleclick.net". Protocols, domains, and ports must match.
Where deltavmap is my site. I've found related questions to this kind of error but none that have given me a solution. The error doesn't seem to appear in anyother browser excpet for Chrome but no ads display regardless. Any ideas? Cheers
Edit: Ads started loading, but the error remains (in fact is prints out every couple of seconds)
