It sounds like you’re encountering a common issue with theme customization on Shopify, particularly with the Dawn theme. The problem you’re experiencing with the “Buy Now” button disappearing when selecting a different variant could be due to a JavaScript issue or a conflict within your theme’s code. Here’s a step-by-step guide to troubleshoot and potentially solve this problem:

1. Check Theme Customization Settings- First, ensure that there are no settings within the Dawn theme’s customization options that might be causing this issue. Sometimes, themes have settings that can hide certain elements based on user actions.

  • Go to the Shopify Admin, click on “Online Store” > “Themes” > “Customize” and review the settings for the product page.

2. Update Your Theme- Ensure your Dawn theme is updated to the latest version, as Shopify continuously improves their themes and fixes bugs in newer versions.

  • To update, go to “Online Store” > “Themes” > “Theme library,” and see if there’s an update available for Dawn.

3. Check the Theme Code- If the issue persists, there might be a JavaScript error or a conflict in the theme’s code that’s causing the “Buy Now” button to disappear when a variant is selected.

  • Go to “Online Store” > “Themes” > “Actions” > “Edit code.” You’ll want to carefully check the theme.js or any other JavaScript files associated with product variants. Look for any errors or conditions that might be hiding the button.

4. Debug JavaScript- Open your product page where the issue occurs in a web browser. Right-click on the page, select “Inspect” and go to the “Console” tab to check for any JavaScript errors. This might give you a clue as to what’s going wrong.

5. Test on a Fresh Theme Install- To rule out any customizations causing the issue, consider duplicating your theme (without any customizations) and testing the variant selection on the duplicate. If the problem doesn’t occur on the fresh theme, the issue likely lies with your customizations or added apps.

6. Contact Shopify Support or a Developer- If you’re unable to solve the issue yourself, it might be time to contact Shopify Support. They can provide further assistance and, if necessary, escalate the issue to someone who can help.

  • Alternatively, consider hiring a Shopify expert or developer who can dive into your theme’s code and fix the issue for you.

Additional Tips:- Review any recent changes or app installations that might have coincided with the issue starting. Sometimes, third-party apps can conflict with your theme’s functionality.

  • Ensure that all product variants are properly configured in your Shopify admin, as misconfigurations here can sometimes cause issues on the product page.
