Hi,
Okay i understand the problem.
Looks like the variable name has changed in VM2.0.22
I have fixed the problem in your website. It now shows 2 category per row.
For those who have the same problem should follow this solution.
Open this PHP file:
/templates/YOUR_TEMPLATE/html/com_virtuemart/virtuemart/default_categories.php
look for this line:
$categories_per_row = VmConfig::get ( 'categories_per_row', 3 );
replace it with this:
$categories_per_row = VmConfig::get ( 'homepage_categories_per_row', 3 );
The problem will be solved.
Regards.
