Widgets/Gadget showing wrong content


Hi Guys, would like to have help regarding this issue.

On the site de-surinaamse-krant.com I made 3 ad units (widgets/gadgets) from the available Basic Gadgets HTML/JavaScriptAdd Add third-party functionality or other code to your blog.

In this space I placed an Adform tag, direct from the ad supplier.

The problem is that when I look at the site sometimes it shows an tag from adspeed, adspeed is an ad-server and there is not an connection with the site and adspeed. In the HTML is nothing from adspeed visible. How can I change this? Kind regards
