Why is my cart page constantly loading on my online store?

Technical Q&A

Topic summary

Cart page on a trial Shopify store is stuck on a perpetual loading spinner, preventing normal cart access from the cart icon on the storefront. The issue appears on the store’s collection page, where customers can add products but then encounter the loading problem when trying to view the cart.

Key findings so far:

  • The temporary cart link shown immediately after adding a product does work.
  • The cart icon triggers the endless loading spinner.
  • A custom setup may be involved: the store uses the Instant Buy & Ajax Add to Cart app, which adds cart functionality on collection pages.

Current troubleshooting status:

  • The store owner suspects the app may be causing the problem.
  • However, disabling the app did not resolve the issue.

Outcome:

  • No confirmed fix was reached in the discussion.
  • The issue remains open, with custom cart behavior or leftover theme/app modifications still a likely cause.

Hi,

We are on trial and trying to set up our store. Our cart page is currently not working and just stays “loading”. Could someone please help?

Hi Jay, the cookies look really delicious!

Have you done anything custom with the add to cart button or modified the functionality in any way? Clicking on the cart icon brings up the spinning wheel (loading) like you said but clicking on the cart link which appears temporarily when you add a product to cart is working fine.

No, we used the Instant Buy & Ajax Add to Cart app to have our add to cart button in the collection page. We were thinking that it might have something to do with the app, but even when we disabled it, the cart page still wasn’t working. Thanks for reaching out.
