Why is my customize checkout button showing an error?

Hello, my customize checkout button is not working. Every time I press to customize it, it says error.

Can someone help me with this?

Hi @livin2424

can you please share the store URL with a password so we can look into it and provide an exact solution?

You want to customize button on checkout page then checkout.liquid is only editable on shopify plus plan.

We cannot edit checkout page in lower Shopify plans.

Hi, @livin2424 .

To confirm, is this the button that isn’t working for you?

I’ve tested the same button on my test store, and it allows me to navigate to the Theme editor just fine to customize my checkout. So it sounds like you might be experiencing a caching issue with the browser that you’re using. To help troubleshoot this issue on your end, can you follow the steps below please?

  1. Try to click on the Customize checkout button via an incognito window.
  2. Or, you can use your usual browser but to clear the browser’s cookies and cache.
  3. You can also try another browser. For example, if you’re using Safari, you can try accessing your Shopify admin on Chrome or Firefox, and to test the button from there.
  4. You can also try to use another device, such as your mobile or a tablet.
  5. Additionally, you can try and access the Customize checkout page via the Theme editor directly. To do so, you can navigate to Online store > Customize. Then, click on the dropdown that says Homepage, and select Checkout. From there, on the bottom left hand corner of the Theme editor, click on Theme settings > Checkout. You should then be able to customize the look of your checkout page from here.

Are you currently in the process of designing your store? If so, I’ll leave some resources below to further help:

Thank you very much, the incognito window worked!

No worries, I’m glad to hear it! It’s worth checking if the usual browser that you use is in need of an update too, as outdated browsers are more likely to have compatibility issues as well as low performance in general. Either that, or your browser may have needed a good clearing of its cookies and cache, so that the Customize checkout button can work again from here on out.
