Hello, where is located the file which is responsible for category products?
I can't see the short description , i have read i need to add the code <?php echo $product->product_s_desc ?> but i don't know the file.
components/com_virtuemart/views/category/tmpl/
copy the file to
your_template/html/com_virtuemart/category/
to make a template override and on this file you can make your changes
