 * Hello there,
 * After yesterday’s update, we are receiving the following fatal error on all posts:
 * >  \plugins\event-tickets\src\Tribe\REST\V1\Headers\Base.php:95
   >  PHP Fatal error:
   > Uncaught Error: Call to undefined function tribe_is_event()
 * We have tried in a separate local environment from our live website, with only
   the twentyseventeen theme and this plugin installed. Please look into this quickly,
   as all websites we have with your plugin that have been updated are down with
   this fatal error as the cause.
 * The /wp-admin/ screens are fine, save for the ones related directly to the plugin,
   so we are able to disable it for the time being.
 * Thank you kindly for your time in reviewing this topic and keep us posted as 
   to when the missing function(?) has been resolved.
 * _For those looking for a temp fix outside of disabling the plugin:_
    `if ( !function_exists('
   tribe_is_event' ) ) { function tribe_is_event() { return FALSE; } }`
 * _Defining a dummy function would hopefully keep things running in the meantime,
   but please note that it may result in unintended consequences or functionality.
   It is recommended you wait for a patch instead, and disable the plugin until 
   one is available._

 * We’re really sorry for the disruption! We just released 4.7.5.1 which should 
   resolve this. Please update and let us know if you hit further problems.
