class:"postbit" not useable anymore ?

[Marv]

Hi, a few days ago I upgraded from 4.0 to 4.0.2. Until this day I had an Adsense Block running (inserted via Andreas TMS and without the use of the AdManager) on a different place instead of the offered ones in vbulletin. So far so good.
After the upgrade I had to notice that the background-color of the table where the Ads are inserted into has gone:



Code used:

PHP Code:

<div class="postbit" align="center">
<script type="text/javascript"><!--
google_ad_client = "pub-xxxxxxxxxxxxx";
/* 728x90, Erstellt xx.xx.xxxx*/
google_ad_slot = "xxxxxxxxxxx";
google_ad_width = 728;
google_ad_height = 90;
//-->
</script>
<script type="text/javascript"
src="http://pagead2.googlesyndication.com/pagead/show_ads.js">
</script>
</div> 


Sounds weird, but could it be that the class."postbit" is gone.. ? All I can see in the stylevars after the upgrade is a class called "postbit_background". Anyone around with a quick and dirty hint for me ?

Any help appreciated.
