 * Dear support,
    Currently using WPv3.7.3. I have tried to install woopos plugin
   and the following error i’m getting when trying to access the edit section of
   this plugin:
 * Fatal error: Call to undefined function WC() in /home/thefreed/public_html/wp-
   content/plugins/woocommerce-pos/admin/class-pos-admin.php on line 320
 * Appreciate any help you can provide. Thanks

 * “Call to undefined function WC()” means that it cannot find WooCommerce. Either
   WooCommerce is not installed or the version is too old.
 * Please note: WooCommerce POS requires WordPress > 3.8 and WooCommerce > 2.1
