Warning: call_user_func_array() expects parameter 1 to be a valid callback

  • Warning: call_user_func_array() expects parameter 1 to be a valid callback, function ‘connect’ not found or invalid function name in /home/zhouruop/public_html/wp-includes/class-wp-hook.php on line 287

    This plugin causes the above warning in WordPress Admin area, when I click WooCommerce -> Order. It also happens when I list all posts.

    Thank you.
