When checking out on the website with a Credit Card customers are either not seeing anything happen at all or they get an internal server error at the top of the checkout page BUT their order is still processed.
I deactivated all plugins and problem was still there so I switched to the basic WP 2017 theme and the problem was not there so I activated just PRO and not the child theme and the problem was not there. I haven’t modified my child theme at all and followed the child theme instructions when I set it up.
Am I missing something here?
Here is a linke the staging site with stripe in test mode where you can see this issue take place: http://agbaby.staging.wpengine.com/
