Text above category image

Joomla3 | Virtuemart 3.04

Can someone help me solve this problem:

I want to lose the text above the categoy-images in maincategories and child-categories.
In older versions (VM2) I created overrides but they just doesn't work anymore.

Already tried an override with /category/default.php like:           <?php /* echo $this->category->category_description;*/ ?>
but then the page turns blank...
