Activating plugin causes error

We’re in the process of moving from a shared hosting solution to an in house server. In the process we’ve updated plugins/wordpress and we’ve been getting the following error.

Warning: session_start(): open(/tmp/sess_5126e28febc335cbcc6b692e2f588ebe, O_RDWR) failed: Permission denied (13) in /home/readystr/public_html/wp-content/plugins/buddypress-media/index.php on line 68

Warning: session_start(): Cannot send session cache limiter - headers already sent (output started at /home/readystr/public_html/wp-content/plugins/buddypress-media/index.php:68) in /home/readystr/public_html/wp-content/plugins/buddypress-media/index.php on line 68

I’ve tried deactivating several plugins with now help. Could this be a bug in the plugin update? Is it possible we have something not configured on the server correctly? Any help would be appreciated.

It seems to be permission issue for /tmp folder on your server.
