Hi,
you have to understand that we can't provide custom template styles for each and every extension that is out there. This is clearly a problem with your extension.
To prove that you can edit file
www.technolab.co.il/joomla2.5/components.../css/layout_2col.css
Find:#jbcontent {
width: 100%;
float: right;
clear: both;
}
Change to:#jbcontent {
width: 100%;
float: right;
clear: both;
height: 100%;
visibility: visible;
}
As you can see, all you had to do is to change css file that belongs to the extension. If you need further assistance with this, please contact extension support to help you with this kind of issue
