I was having issues with the cart button constantly loading so looked for a solution online, I edited code to try and fix this but now I getting " Parameter Missing or Invalid: Required parameter missing or invalid: items " error - would someone be able to help me please?
I see what you are going through. You should share your store URL so I can take a look at the error and the source of error so I may be able to help you or give you a direction.
I see the error, that’s probably because you messed up with the theme.js or cart.js file. You probably deleted (or modified) the script to add the product to the cart. There are some more issues too like the dropdown in the menus not working etc. I can help you with it but it will require taking a look at the backend. Contact me if you need my help.
I am having similar issue when I add product to Cart and from Top menu click on my cart which brings sideview cart window and I try to delete product right away. My store is www.lavenderandblues.com . Could you check please. thanks!!
