 * We are getting 2 error warnings:
 * 1. Warning: call_user_func_array() expects parameter 1 to be a valid callback,
   function ‘woocommerce_price_filter’ not found or invalid function name in /home4/
   island/public_html/wp-includes/plugin.php on line 192
 * 2. Warning: array_unique() expects parameter 1 to be array, null given in /home4/
   island/public_html/wp-content/plugins/woocommerce/includes/class-wc-query.php
   on line 357
 * Any suggestions would be greatly appreciated.

 * The issue was a result of having an older version of the Maya Shop theme installed
   with the newest version of WooCommerce. Upon updating the theme to the most recent
   version, these warnings went away.
