Hi,
1- To disable the "drop down shopping" that comes with PureMart and get back to original VM - Shopping Cart module. Through FTP, find this folder:
ROOT//templates/YOUR_TEMPLATE/html/mod_virtuemart_cart/
and rename it to:
ROOT//templates/YOUR_TEMPLATE/html/mod_virtuemart_cart2/
You will get back to official VM - Shopping Cart module (which shows the products in the cart only, there is no drop down effect)
2- To disable modal popup, open your joomla backend and navigate to here:
VM Backend >> Configuration >> Checkout
in this page, look at the 1st option and disable it: Display modal popup upon 'Add to cart'
The visitor will be directed to shopping cart once they click the "add to cart" button.
Regards.
