This plugin is needed for mobile ticket scanning. The error code is below (shows up on user profile page). Help!

Hi there,

The reason you’re seeing the fatal error is because your site’s version of WordPress (4.2.20) does not include the REST API. You’ll need to update your site to the current version of WordPress (or at least WordPress 4.7) before you can use the apps and plugins like Application Passwords.
