Visual Editor Troubleshooting: Iframe Compatibility

Resolve Infinite Redirects and Loading Issues When Using Convert’s Visual Editor on Iframe-Restricted Sites

IN THIS ARTICLE YOU WILL:

🔭 Overview

Convert’s Visual Editor loads your website inside an iframe to enable seamless editing and experiment configuration. However, some websites implement restrictions or have frontend logic that was not tested inside an iframe, causing issues such as:

    • Infinite redirect loops (not only on login-protected pages)

  • JavaScript errors or heavy AJAX reloads

  • Blank or unresponsive editor screens

💡 Common Scenario

If your website uses a web-based login form (instead of basic HTTP auth), the login page may redirect continuously when opened in the Visual Editor. Even if iframe protections like CSP or X-Frame-Options are bypassed during VE loading, some JavaScript or server-side logic may still misbehave in an iframe context.

✅ How to Diagnose

To test this independently:

  1. Open a blank HTML page on your own domain.

  2. Embed your website using an <iframe> tag.

  3. Observe the behavior in Chrome’s developer tools (Network tab).

  4. If you see multiple AJAX requests or continuous redirects, the issue lies with the website itself—not Convert.

Alternatively, use free tools such as https://iframetester.com to load your website in an iframe and verify if it behaves as expected.

🔍 Example from Convert QA Team

Our developers tested such cases and observed:

  • Massive AJAX calls were triggered solely due to iframe embedding.

  • The site logic "breaks" when iframed, even outside Convert’s tools.

🛠️ Recommendations

  • Ensure your website behaves normally when embedded in an iframe.

  • If login is required, consider:

    • Allowing public access temporarily for setup

    • Using Basic Auth (HTTP Authentication) instead of form-based login

    • Working with your dev team to support iframe rendering for internal/test environments

⚠️ Important:

Convert cannot resolve iframe-induced logic issues from your website’s side. These must be handled by your development team.

It's crucial to investigate and resolve iframe-related issues early in the troubleshooting process, as they are very likely to be the underlying cause of other problems in the Visual Editor.
