There is a JS error when 'add to cart' clicked.
Please check browser console for more details, and to fix this you have to manually check your code.
You have a jQuery version collision and hence an error is thrown when trying to add to cart. The code assumes jQuery of at least 1.12.* (where jQuery.post( [settings ] ) has been introduced), but the code is being executed against jQuery 1.11.1 where this method doesn't exist.
Looks like you've recently installed an app that added jQuery version 1.11.1 as dependency and broke your store's functionality. Had a quick look and it seems like the app is SCM Product Label.
In your Theme Code editor, layout/theme.liquid, try finding the lines that have either scm-product-label.js or scm-product-label.css and comment/remove them.
@DEDE_32 can you share an URL to a
product page that has no Add To Cart button?
Hello I need an expert coder to fix the Java Script issue on my shopify page. The add to cart button is no longer working. I uninstalled recent apps and it still doesnt work.
@marcusnewtothis add to cart works for me on Chrome, I see no issue. Is this happening on a specific page? On what OS/Browser you see this happening?
