Hi Graeme, just sent you an email through your email link on here, hope thats ok.
I think the new site structure is the key, what happened here is i imported the new feed and then noticed that a lot of my pages had missing thumbnail images so went back to the old feed. Then when i started clicking through the site (as i was about to start a new ppc campaign) i started getting these errors. I never checked again with the new feed and of course when i checked on another site that hadnt been updated the same errors occur.
I think this might mean then that anyone who has'nt updated their feed since Friday may be experiencing the same issues?
Regards
Graahm
