Add to cart not working - Dawn Theme

Topic summary

Issue: Multiple users report non-functional “Add to Cart” buttons on Shopify stores using the Dawn theme.

Initial Solution (RasmusUG’s case):

  • Problem resolved by removing specific CSS code from the global.js file
  • Steps: Store Admin → Online Store → Themes → Edit Code → Open global.js → Delete problematic CSS at bottom → Save
  • A screenshot was provided showing the exact code to remove

Additional Cases:

  • Rainmaker: Experiencing site-wide cart button failures across different themes

  • Suggested fix: Disable the “Zipify OneClickUpsell” app via Theme Customize → App Embeds

  • Emily622: Cart button stopped working after theme update and option set changes

Status: The original issue is resolved, but similar problems persist for other users with potentially different root causes (conflicting apps, theme updates). The thread remains active with ongoing troubleshooting.

Hi @RasmusUG

Please try going to your store admin > Online Store > Themes > Edit code > opening the global.js file, going to the bottom, removing this CSS code from your file, saving it, and checking again.

Hi Dan,

I’m having the same problem: (. I recently updated my theme and made some changes to the option sets, and now my cart button isn’t working. Can anyone help figure out what’s wrong?
