Would it be ok to get a copy of your site to test here locally?
It will be much easier for me to work on a copy rather than the live site where I can disable plugins and check your theme etc without breaking your live site.
In the beginning, I thought it was a different problem, because I had no woocommerce cart page (my cred form should redirect to checkout) and as a result after the submission of the cred form the user was redirected to the main page. Yesterday I did set up a cart page and now the user will be redirected to the woocommerce cart page, where it says that the cart is empty... hidden link
thanks Shane- I just got pinged by the wp-engine banned plugin bot about a copy of duplicator. Not sure why they dont like it but assume that's you and i'll remove later today
