Due to reverse proxy nature of browser-sync, some things like WordPress Customizer and REST API may not behave correctly when opened from the proxy URL.
This happens during development time only and has no side-effect on your production server.
To fix it, add the following snippet in wp-content/mu-plugins/wpackio-fix.php
of your local development server.
<?php
add_action( 'rest_api_init', function() {
remove_filter( 'rest_pre_serve_request', 'rest_send_cors_headers' );
add_filter( 'rest_pre_serve_request', function( $value ) {
header( 'Access-Control-Allow-Origin: *' );
header( 'Access-Control-Allow-Methods: GET' );
header( 'Access-Control-Allow-Credentials: true' );
header( 'Access-Control-Expose-Headers: Link', false );
header( 'Access-Control-Allow-Headers: X-Requested-With' );
return $value;
} );
}, 15 );
add_action( 'customize_preview_init', function() {
add_filter( 'wp_headers', function( $headers ) {
$headers['Content-Security-Policy'] .= ' 192.168.1.144:3000';
return $headers;
} );
} );This is for your development server only. DO NOT add it to your production server.
