When I click ‘check out’ after adding an item to my cart, the button redirects me back to the cart instead of to the checkout form. I’ve realized that this only occurs with the check out button on the ‘cart’ page and not with the check out button in the ‘cart pop-up’ notification which appears when you add an item to cart. Here is the store link: https://kaiuru.com/.
It looks like you are getting a checkout error from printful. It seems to not be recognizing your checkout form. Have you edited the theme file code for that page? Are you using Printufl? Or any other apps affecting checkout?
Turns out printful was used for one of my other stores, I just uninstalled it along with Alireview, but so far it hasn’t changed anything. The check out button still sends me back to the ‘cart’ page.
