Hi ​@ellabella - sorry to hear you are having this embed issue. Here is a few things you should check that should help resolve the issue. 

1. Double-check embed placement: Make sure the Klaviyo embed form code is placed inside a Custom HTML block in Shopify’s theme editor, not just pasted in the page content or rich text blocks. Shopify sometimes strips code from those areas.

2. Verify publish status: Go to Klaviyo > Signup Forms and make sure the form is published. If it’s in “draft” mode, it won’t render.

3. Check display targeting: If the form is using display rules, make sure it’s set to show on “all pages” or the specific URL you’re testing. Sometimes forms are restricted by URL paths or audience targeting.

4. Confirm site tracking is working: Open your Shopify site, right-click > View Page Source, and search for klaviyo.js. If it’s not there, your site may not be properly connected to Klaviyo. You can reinstall the Klaviyo app from the Shopify app store to ensure proper integration.

5. Script conflict: Occasionally, other Shopify apps or custom scripts may interfere with Klaviyo embeds. Try previewing the theme in safe mode or duplicating the theme and disabling custom apps/scripts to test.

6. Use Klaviyo’s Preview Tool: Inside Klaviyo, you can click into the form and use the “Preview” tool to see if it renders outside of Shopify. This helps confirm if the issue is with Klaviyo or the embed location.
