I just placed adsense referral ads on my site and they are not showing up at all. It has been over 30 minutes and nothing there. All other ads work fine.
this happens once in a while, but it's happened several times in the last few months.. 2 or 3 weeks ago i didnt see my (firefox) referral buttons for over a week..
I think there was some update (about month ago), it was something like only US publishers can promote adsense refferal program, Im not sure but try to use search option in this forum and Im sure you find the answer.
Google advertisements could only be integrated thrice per web page. Maybe you have exceeded the limit.. Kindly check...
I have this same problem. I have one regular AdSense ad and one referral ad. Just a blank space is showing up, even though I set it to automatically choose fallback ads. It's working fine for all my sites except in just one case. Tried creating a new referral ad but still doesn't work.
I've had it happen when the Adsense code isn't spread out across several lines. In other words, when saving the page, the code can get compressed into "one long sentence", so to speak.
@usasportstraining - maybe if you use some kind of formatting (like for ex Joomla WYSIWYG editor or any other vis editor) try turning off code cleanup @netpox - maybe, just maybe you're not from the targeted country for ref ads, or clean cache or disable firewall and/or antivirus and try again ?
