 * Hi Taylor,
 * This could be a hiccup in our server, for all I know, but got this notice from
   our server cron daemon and thought I’d pass along in case it helps:
 *     ```
       Warning: Missing argument 2 for SC_Advanced_Cache::purge_post_on_comment_status_change() in /home/user/public_html/cms/wp-content/plugins/simple-cache/inc/class-sc-advanced-cache.php on line 47
   
       Fatal error: Call to undefined function WP_Filesystem() in /home/user/public_html/cms/wp-content/plugins/simple-cache/inc/class-sc-advanced-cache.php on line 57
       ```
