Not sure if I am using a load balancer.. maybe NginX is a load balancer out of the box?
I created a sessions/ in my wordpress install folder and tried to update wp-config.php and index.php with: session_save_path('/home/deployer/sites/ec2-54-226-138-235.compute-1.amazonaws.com/sessions/');
Restarted NginX but no luck. Any insights?
