Required parameter missing or invalid: items

[lilithandselene]

Hi, I keep getting this error 

Required parameter missing or invalid: items

When attempting to add items to cart. Link is: https://lilithandselene.com/

Based on other similar solutions, the code looks complete to me (I'm no expert though). And I've deleted a few apps to see if it's them causing it, but so far no luck. Any help would be fantastic!

I'm using the Dawn theme.

Thanks in Advance

Hi @lilithandselene  while looking at your store I don't see any error please try to add to cart from another browser or in an incognito window or try removing the cache and cookies of the page in a browser.

Thanks
