 * Hello there,
 * We’re receiving a lot of PHP warnings on our backend:
 * `Parameter 1 to Groups_Admin_Posts_Legacy::parse_query() expected to be a reference,
   value given`
 * This warning can sometime be fired over 50 times and has a negative impact on
   admin page load.
 * It looks like it is related to the use of Groups with some WooCommerce plugins:
 * -> woocommerce-customer-relationship-manager
    -> woocommerce-order-status-manager
 * Could you please check this?
 * Thank you!

 * Hi,
 * Thanks for reaching out!
 * If this is still an issue with these plugins, I would first recommend to upgrade
   following the [Migration Guide](http://docs.itthinx.com/document/groups/migration-guide/).
 * Cheers
