 * Hi,
 * I saw this notice on my woocommerce status:
 * The “woocommerce_debug_posting” hook uses out of date data structures and is 
   deprecated since version 3.1.1! Use woocommerce_system_status_environment_rows
   instead. in /home/content/a2pnexwpnas04_data02/88/3327588/html/wp-includes/functions.
   php on line 3831
 * what does this mean? and how do I fix this issue?
 * Thanks
