First of all; CleanMart comes with 1 standalone module and it is called:
Flexible - Virtueamart 3 Dropdown Shopping Cart
but CleanMart also comes with "template override" for official VM - Featured Product Module. So, it means you are still using Official Virtuemart Product Module, but CleanMart overrides the module and enable the slider in the front-end.
If you end up with a jquery conflict error or faulty functionality; you can disable the CleanMart overrides and get back to original VM - Featured Product Module by renaming this file:
/templates/YOUR_TEMPLATE/html/mod_virtuemart_product/
to
/templates/YOUR_TEMPLATE/html/mod_virtuemart_product2/
Secondly; (for the error messages) follow these steps:
- Install plg_FlexibleVm3cart.zip to your Joomla
- Find the "Flexible - Virtueamart 3 Dropdown Shopping Cart - Plugin" through the Joomla Plugin manager.
- Publish the plugin (don't forget to publish it)
- open this PHP file:
\modules\mod_flexible_vm3_cart\mod_flexible_vm3_cart.php
to the top (after <?php line) include this line:
$css_product_per_row = $css_cart_label = $checkAutomaticPS = '';
and you won't see the "undefined variable" error messages anymore.
Regards.
