I continually get 403 Forbidden on ads on one type of page on the site. All other pages are fine.
For the purpose of illustration: [englishforums.com
I removed all the elements in the page leaving just the ad block, same error.. What's strange is that if I copy the html source into another page, running it from the desktop it works. Ie: It appears that the URL of my site is causing a problem.
^^ The generated url that causes the 403 error.
Any ideas, I'm at my wits end,
