Public-Notes for problem fixing - related to WordPress and Tools

Public Notes for everyone and me to remember how Problems are solved

webvizio.com and WordPress Problem fixing

1. On your hosting service provider or service Panel (GridPane.com) disable the clickjacking protection
2. Install the plugin https://github.com/PHPWatch/WordPress-SameSite (Click on the green code button, download as Zip, upload as Plugin)
3. add these lines to the functions.php

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

4. add this to wp-config.php

define('WP_SAMESITE_COOKIE', 'None' );

This above

• Allows you to display the site with the login page and the administrative panel in a frame
• Give opportunity to use all cookies including session cookies in iframes. If third parties do not know your admin area passwords, the only security problem is displaying your pages in a iframe, but they are protected by login + Wordpress by default allows you to display the site pages in iframe
