My website has been validating fine since I joined the coop ad network and suddenly now it won't validate. The system says it cannot find adverts on my homepage - I can find them, they are right there and working fine. What's going on??!! My URL: http://www.infobite.co.uk If this continues I'll have to leave the Coop Ad Network, as all I am doing currently is adding outgoing links to my website for no return links! My google ranking is in danger if this continues!
Not able to find out why. Use their customer support. I don't think any one will click those ads. Anyways, best of luck.
