I'm a new comer to WAMP server and also have attempted to set up it but after setting up it after i check it by visiting localhost url within the browser it's not working. I get a 404 error and blank page.

Please tell me how you can solve this.

Click the WAMP server icon and in the menu under "config files" choose "httpd.conf". A lengthy text file will open in notepad. Within this file scroll lower towards the line that reads "Port 80" and alter this to see "Port 8080", Save the file and close notepad. Once more click the wamp server icon and choose restart all services. Yet another change must be made before we're done. In Home windows Explorer discover the location where WAMP server was installed that is automatically "C:Wamp".
