Widget not loading on my website

Diagnose why the embedded store locator is blank or not appearing.

Last updated April 27, 2026

If the widget is blank, broken, or not appearing on your site, work through these checks in order.

1. Confirm the snippet is intact

Open the page source in your browser (View Source or right-click → Inspect) and search for "maptera". The full iframe tag should be present and unmodified. If your CMS stripped any attributes, re-paste the snippet from your dashboard.

2. Check the iframe height

The most common cause of a "blank" widget is a height of 0. Make sure the iframe has an explicit height attribute (recommended: at least 500px) or that its parent container has a fixed height.

3. Open the iframe URL directly

Copy the src URL from the iframe and paste it into a new browser tab. If the locator works in isolation, the issue is on your hosting page (CSP, theme conflict, etc). If it does not work in isolation, the issue is in your Maptera account.

4. Look at the browser console

Open DevTools → Console. Errors mentioning "blocked", "CSP", "X-Frame-Options", or "mixed content" point to a security policy on your site blocking the iframe.

If you are still stuck, email maptera@switchlabs.dev with the URL of your page and a screenshot of the browser console. We respond within one business day.
