After successfully installing and configuring wampserver 2.2, I was using PHPMyAdmin with Listen 80 and ServerName localhost:80 configured in httpd.conf Then for some unknown reason, after starting wampserver, I got 404 page error on localhost. After some research on forums, I changed httpd.conf to Listen 81 and ServerName localhost:81. I still got the 404 page error until I changed localhost
