I choose AFW car for a site (Joomla 1.5) and got crazy because it doesn't display error, notice etc in the coloured bar like usual. After some search I found the solutione, here it is for everybody has the same problem:
I also added a breadcrum position that is missing ad put there th code to let the message disply possible.
In index.php of the template I added this lines
<jdoc:include type="modules" name="breadcrumbs" style="none" />
<jdoc:include type="message" />
