I have the latest versions of all things WP but when I activate the Woocommerce plug in I get this message Warning: session_start() [function.session-start]: open(/tmp/sess_d1qab13le8bve2n18906o5sid7, O_RDWR) failed: Permission denied (13) in /home/csiaccess/vitatech4life.com/wp-content/plugins/woocommerce/woocommerce.php on line 138
If I deactivate, it goes away.
