Hello,
WooCommerce has option to disable the Ajax add to cart on the shop page http://prntscr.com/p5pwh2 but WPBakery plugin affects this option and does not allow to disable Ajax no matter is option is enabled or disabled. Somebody reported about this long time ago https://codecanyon.net/item/visual-composer-page-builder-for-wordpress/242431/comments?page=807&filter=all#comment_16729393 but looks that have not fixed this yet. We contacted them again to get fix. I’ll inform you once we get any helpful answer. So, it’s not our theme issue but WPBakery plugin bug.
Regards
