# PHP error on activation

 * A plugin like this is just what I need for a client site, but it doesn’t work
   correctly for me out of the box. After installing and activating I see the following
   error:
 * Uncaught Error: Call to undefined function WP_Plugins_Core\as_next_scheduled_action()
   in /wp-content/plugins/resize-image-before-upload/vendor/tmmtech/wp-plugins-core/
   src/class-notifications.php, line 74
 * This may have something to do with the included Action Scheduler, or with the
   WP_Plugin_Core package, or the way the undefined function is being called.
 * I’m using WordPress 6.2. None of the other plugins that I have installed use 
   WP_Plugin_Core or Action Scheduler (no WooCommerce on this site, or any other
   plugin that uses these components).
 * Has the plugin developer or anyone else seen an error like this? Any idea what
   to do?
