Ads banners disappear in the main content area

dear ACME Themes supporter,

i have the same problem like described in this thread :
https://www.ads-software.com/support/topic/my-ads-are-now-showing-upp/

The problem was obviously solved, but unfortunately the solution was not posted. That’s why I’ve opened a new thread now.

following problem :

in advance, i use the same advertising network from the above thread, this is Chitika (similar to Goggle Adsense).

i use HTML widgets to add advertising codes which normally works fine. when i add the chitika code in the header or footer area, the banners will be displayed correctly – but when i add them into main content area or sidebar widget, the banners are displayed for a few seconds and then disappear suddenly.

the banner will be visible until something is finished loading from “pagead2.googlesyndication.com” or similar source (to be seen in the browser bar).

you can see that on my website (right in the sidebar above under “Advertising”)

i have tested this with the latest firefox and google chrome browsers, deleted cache and cookies and so on, deactivated several widgets and plugins, but always the same result like described above.

if I embed a java code from other advertising providers at this point, however, these will be displayed correctly.

if it helps, that’s what the chitika code looks like :

<script type="text/javascript">
  ( function() {
    if (window.CHITIKA === undefined) { window.CHITIKA = { 'units' : [] }; };
    var unit = {"calltype":"async[2]","publisher":"account_name","width":300,"height":250,"sid":"Chitika Default"};
    var placement_id = window.CHITIKA.units.length;
    window.CHITIKA.units.push(unit);
    document.write('<div id="chitikaAdBlock-' + placement_id + '"></div>');
}());
</script>
<script type="text/javascript" src="//cdn.chitika.net/getads.js" async></script>

thank you in advance for your help

Patric
