Thread: why is my iframe ads not displaying in 1 site but displaying in another?

why is my iframe ads not displaying in 1 site but displaying in another?

I dont know where possible went wrong... I have a few sites using classipress. The problem I encounter is that I signed up with ads serving network to display sponsored ads in my site. These ads serving companies provided me their ads code (tag) in iframe, which I inserted them in my Text Widget under my main page and ads page. However, these ads serving networks "sponsored" ads is not displaying. I insert the every same code into another site (also using classipress, same WP version, Same Classipress Version) and it worked. I am puzzled and need assistance to see where went wrong for this site? (www.hapiclub.com) - do not display iframe ads..
