The problem is the x-frame-options setting on the tracked site. That setting specifically disallows your website to be displayed inside an iframe on external domains.
This is the error: "site could not be displayed in a frame because it set 'X-Frame-Options' to 'sameorigin'. "
Solution A: Set the correct HTTP headers
Best way is to add the correct headers to the tracked site. Those headers will allow only the userTrack dashboard domain to load your website in an iframe.
If you are using Apache, edit .htaccess
<IfModule mod_headers.c>Header always set X-Frame-Options "SAMEORIGIN"Header set Content-Security-Policy "frame-ancestors 'self' analytics.your-usertrack.net;"</IfModule>
If you are using Nginx, add this line to your site's configuration:
add_header Content-Security-Policy "default-src 'self'; frame-ancestors 'self' analytics.your-usertrack.net;";
Solution B: Disable the browser security policy (Not recommended)
Another, easier solution is to use a browser extension to display this security policy:
