 * I see two messages popping up in debug.log which seem to come from fastest cache:
 * Notice: Undefined variable: order_arr in /home/public/sites/www.benlinders.com/
   wp-content/plugins/wp-fastest-cache/inc/preload.php on line 161
 * Notice: Undefined property: stdClass::$go in /home/public/sites/www.benlinders.
   com/wp-content/plugins/wp-fastest-cache/inc/preload.php on line 440
 * Happening about every 5-10 minutes.
 * Any idea what causes this?
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Ferrors-in-debug-log-undefined-variable-property%2F%3Foutput_format%3Dmd&locale=en_US)
   to see the link]_
