 * On a site I use for plugin development, I just started seeing this:
 * `PHP Parse error: syntax error, unexpected '|', expecting ';' or '{' in /[..]/
   public_html/wp-content/plugins/wp-cron-pixie/includes/class-cron-pixie.php on
   line 460`
 * The site is configured to use PHP-FPM 7.4. The WP Cron Pixie version is 1.6.1.

 * This error occurs due to the `bool|WP_Error` return construct for several functions
   in that file. AFAIK, this style of function declaration isn’t compatible with
   PHP 7.4.

 * Oops, sorry about that [@joho68](https://wordpress.org/support/users/joho68/).
 * WP Cron Pixie v1.6.2 has just been released with a fix for PHP 7.4 compatibility.
