Oh

Oh boy, well I am getting a fatal error all of the sudden and some subsites are not working.

PHP Fatal error: Call to undefined method ProSites::get_profile_id() in /home/mysite/public_html/wp-content/plugins/pro-sites/pro-sites-files/gateways/gateway-paypal-express-pro.php on line 3146, referer: /wp-admin/network/sites.php
