Product removed and Add to cart not working

[dogmansa]

Hi

Using Joomla 3.9.11 and VM 3.6.2

I am experiencing a strange problem since upgrading to VM 3.6.2

If I click add to cart on any product on the browse page, I get the product removed alert and the page goes to the cart but no product is added. The usual modal window with product added to cart is not displaying either. If I go to the product page, the add to cart works fine.

If I disable display modal popup upon 'Add to Cart' I am able to add products with no problem.

Is there a way to fix this perhaps?

Thank you for any assistance

will be a JS error in your template ... track it down in the console..

fix by comparing the new core templates and yours

Wow. Thank you for the quick response. Could you perhaps point me in the right direction. Not sure how to attempt your repair. Will it be the template files?
