I just checked my account, and it was disabled, apparently the system couldn't find the ads on some pages on my site (it's running on all the pages) I had it recheck, and it complained about a page that doesn't exist on the site anymore (and thus, no ads). Ran it again, and it complained about a second page that didn't have any ads (again, that page is no longer on the site). Both of those pages return a 404. Something I need to be doing here? Should I be concerned?
Add the following code to your .htaccess file ErrorDocument 404 http://www.your-site.com Code (markup): This will redirect the 404 traffic back to your main index. Should take care of your problem.
Instead of redirecting to your homepage, you can also make a 'new' 404 error page with a small sitemap to help your users (if they find the non existing link) and put ads on the 404 page in your .htaccess (or httpd.conf) ErrorDocument 404 /404.html Code (markup):
