Hello Daniel,
Thanks for reaching out to us.
The X-Frame-Options header is a server-side security setting that prevents a site from being embedded inside an iframe to protect against clickjacking attacks. This behavior is controlled by the server or hosting configuration, not by Helix Framework or SP Page Builder.
You may need to check your server configuration, .htaccess file, or hosting control panel to adjust or remove the X-Frame-Options header if necessary.
We recommend contacting your hosting provider or server administrator for assistance with modifying this setting.
Thanks.
