Troubleshooting: Embedding Issues

Fix problems when embedding FormRobin forms on your website using iframes.

Common Embedding Problems

  • Form doesn't appear in iframe
  • "Access denied" or domain error
  • Form cut off or wrong size
  • Form works standalone but not embedded

Issue: Domain Not Whitelisted

Symptoms: Blank iframe, access denied message, form loads on FormRobin but not your site.

Solution:

  1. Go to SettingsDomains
  2. Add your website domain (e.g., example.com)
  3. Include www. version if applicable
  4. Save and test again
  5. Wait 1-2 minutes for changes to propagate

Issue: Incorrect Embed Code

Solution:

  1. Get fresh embed code from FormRobin
  2. Copy the entire <iframe> tag
  3. Don't modify the src URL
  4. Paste exactly into your website HTML

Issue: Form Cut Off or Wrong Size

Solution:

  1. Adjust iframe height attribute (e.g., height="800")
  2. Set width="100%" for responsive width
  3. Remove any CSS that restricts iframe size
  4. Test on mobile and desktop

Issue: Content Security Policy Blocking

Symptoms: Browser console shows CSP errors.

Solution:

  1. Add forms.formrobin.com to your CSP frame-src directive
  2. Example: Content-Security-Policy: frame-src 'self' forms.formrobin.com;
  3. Contact your website administrator if unsure

Issue: Mixed Content (HTTP/HTTPS)

Symptoms: Iframe blocked on HTTPS site.

Solution:

  1. Ensure embed code uses HTTPS URL
  2. FormRobin URLs should start with https://
  3. Don't embed HTTPS content on HTTP pages

Issue: Browser Cache Showing Old Version

Solution:

  1. Hard refresh: Ctrl+F5 (Windows) or Cmd+Shift+R (Mac)
  2. Clear browser cache
  3. Test in incognito/private mode
  4. Try different browser
