First of all, adding to cart should be implemented fully as AJAX (pls, refer to Woo's manuals).
Pls, remove this in https://www.s-sols.com/docs/wordpress/accelerator/settings-accel/settings-users-accel#dep_grp
and test all adding to cart flow to ensure. If it doesnt work, pls, revert the settings or setup full AJAX cart management.
