How to fix a Klaviyo signup form not showing on your site

A Klaviyo form that does not appear is usually set to draft, blocked by its targeting or timing rules, hidden because the visitor already saw it, or not loading because the onsite script is missing. Check each in turn and test in a private browser window.

Have this ready.

• Access to the form and its settings
• The page address where it should appear
• A private or incognito browser window
• Knowledge of any recent theme or app changes

Steps.

1. 1. Check the form status

   Open the form and confirm it is live, not a draft. Edits may also need publishing before they show up on the site.

2. 2. Review the display rules

   Read the targeting settings for pages, devices, timing and scroll. A rule that is too narrow can mean it never meets its conditions.

3. 3. Check the visitor rules

   Forms often hide for people who already subscribed, or who closed the form recently. Test with a fresh private window to avoid this.

4. 4. Confirm onsite tracking loads

   Make sure the Klaviyo script is on the page. If it is missing, forms cannot render, and it often vanishes after a theme change.

5. 5. Look for conflicts

   Check for other popups, cookie banners or page builders that could cover or block the form, and try on a different device.

6. 6. Clear caches

   Clear any site cache or CDN cache so visitors get the latest page, then reload and wait for the timing rule to trigger.

7. 7. Test submission end to end

   Submit the form with a new test email and confirm the profile lands on the right list with the expected consent.

Common pitfalls.

• Testing in a browser where you already dismissed or submitted the form.
• Assuming a saved form is a published form.
• Not noticing the script was removed during a theme update.
• Setting delay and scroll rules that conflict.

Check it worked.

• Form is live
• Display rules match the target page
• Onsite script loads on the page
• Private window test shows the form
• Submission creates a profile on the list

Klaviyo changes its interface from time to time, so treat the steps as the order of work and match the names to what you see on screen.
