 * Hello,
 * Upon restoration of my Updraftplus backup, I got a php notice about WP Optimize
   in the log:
 * PHP event: code E_WARNING: call_user_func_array() expects parameter 1 to be a
   valid callback, class ‘WP_Optimize_Commands’ does not have a method ‘_post_action’(
   line 18, wp-content/plugins/wp-optimize/includes/class-updraftcentral-wp-optimize-
   commands.php) (jun 21 11:28:55)

 * I think that’s just a one-time message caused by a change in version of installed
   plugin, and nothing to be concerned about.
