I have changed the way I redirect URLs have so I've decided to change to Interstitial Ads.
However, when the "Interstitial Ads" load up, the links I have added (1 per line) do not show up. Instead it displays the short url site and states "This short url is no longer active"
What would cause this? I've replaced the .htaccess, interstitualAd.php and interstitualAdTop.php to the original files but this does not fix it.
