Hello: I tryed to search for this topic but I could'n find any.
So here we go.
I'm using Joomla 3.6.0
With Virtuemart 3.0.16
PHP 5.6.21
When I use manufaturers the system does not give back any product. Just the starting category.
If I turn off Friendly URL and Overwrite, the manufacturer URL give me this without any results
SITE/index.php?option=com_virtuemart&view=category&virtuemart_manufacturer_id=2&Itemid=116
If I edit the line and take away the Itemid code, the VM shows me the products for the manufecturer.
SITE/index.php?option=com_virtuemart&view=category&virtuemart_manufacturer_id=2
Itemid is the current Menu item.
So... What I'm doing wrong??
Itemid=116, is this a link to the category or root of virtuemart(main page) ?
If it's a category, this can be a trouble and filter by category & manufacturer.
Anothe potential problem, is that the function mean that your manufacturer is a category(i have the same problem when you use sef with a plugin link, VM mean the "plugin" part is the name from a caetgory and fails to find the good route).
