Hi NG, Well, as the title already says: My ISP does not allow access to another domain from the PHP script or via SSI. I tried the following workaround, but that didn't work either. I put the script on another server with another domain where I don't have this restriction and tried to call it from my "restricted" website. This happened: - Doing so in a frame or iframe displayed the ads, but the COOP doesn't recognize that they appear on my website and therefore doesn't calculate a weight... Doing so outside a frame (via SSI) doesn't work either because my ISP doesn't allow includes from another domain and/or server, too. I'd be happy if someone could give me an advice. Changing to another ISP is the worst option at this time. Thank you very much! Thomas P.S. If it helps this is the restricted domain: http://eurocomp.info
