Cannot access phpMyAdmin on webserver running Nginx + Apache

When you choose to activate Apache + Nginx, the phpmyadmin cannot be accessed. It will force you to download a blank index.php instead of displaying phpMyAdmin page.

Sorry to resurrect a dead (or at least dormant) topic but I'm having the same problem and wondered what the solution was.
