Ok, I am trying to run the ads on a custom error page because for some reason the network is not validating because ads are not on pages that don't exist. The error pages have to .html and I don't think they will be covered by a htaccess file. So I can't do a rewrite. Does anyone have any ideas?
The ads come from the Google API search. Therefore, you may have pages cached in Googles system that do not exist. I would do 1 of two things. 1. Have Google remove those pages from the cache which could take a little while. 2. If there are not too many recreate those pages manually, put them back in the directory where it is looking for them at, place the ads on them and you should validate. Over a period of time, Google will find out that those pages do not exist anymore because they are not reachable from any of your other pages and will remove them from the cache. Just a suggestion.
