How To Get WordPress To Open A New Page In An iFrame

Author: erics, July 30th, 2011

Edit the file wordpress/wp-includes/functions.php and just comment out the line in the middle:

function send_frame_options_header() {
    //@header( 'X-Frame-Options: SAMEORIGIN' );
}

function send_frame_options_header() {

//@header( 'X-Frame-Options: SAMEORIGIN' );

}

UPDATE: Based on Brent’s comment, here is a better solution:

remove_action( 'login_init', 'send_frame_options_header' );
remove_action( 'admin_init', 'send_frame_options_header' );

1 2	remove_action( 'login_init', 'send_frame_options_header' ); remove_action( 'admin_init', 'send_frame_options_header' );
