Total newbie here. I hope this is the correct forum section for this thread.
I've been setting up my Shopify store, things all seemed to work about a week ago, but then yesterday I added a bunch of new items and did some layout editing, and now all of a sudden, when I click to go to the checkout page, I get this error: Parameter Missing or Invalid: Required parameter missing or invalid: items.
Does anyone know what could be causing this problem? Any help would be greatly appreciated!
Oh, and I am using the Simple theme.
Solved! Go to the solution
I'll just give the store link: https://est-sark.myshopify.com (for some reason the "Share Preview" tab is not showing up for me at the moment).
The store is in a foreign language though. I'll provide translations if necessary.
Looks like the issue is caused by this app - https://apps.shopify.com/easy-terms-conditions-pop-up . For whatever reasons, once you check the agreement in the TOS popup and click the button to accept, it tries to do a call to the add to cart endpoint with no parameters, hence the error message.
