WAMP server in green but only get 404

Question

Alright ladies and gents. I have quite the puzzling issue. I have WAMP server installed on my WIN7 machine at work, everything was working fine and dandy. Didn't use it for a few weeks because I got pulled into other things. The other day I tried to start it up... The icon was green and I figured we were good. Then I tried to open up localhost and just get a 404 error:

HTTP Error 404. The requested resource is not found.

I have no clue why it's doing this, we were working fine 2-3 weeks ago and now nothing. Have any of you had the green icon but couldn't get any pages to come up? Where in the heck do I go because I'm beating my head against the wall here.

Thanks in advance.

Answer 1

It is also possible that some other service is running on port 80 (maybe IIS Express, some Torrent clients, Skype..). A solution could be to change the port on which is being listened (as Mithun Sen has said).

So change the port on which Wamp listens:

• Click on Wamp server -> Apache -> httpd.conf
• Change Listen 80 to something else, eg: Listen 81
• I would also change ServerName localhost:80 to ServerName localhost:81

If you've done this, and saved httpd.conf, you have to restart the Wamp server. Then use localhost:81 as your root url.

So the urls will then look like

localhost:81/phpmyadmin
localhost:81/mysite_directory

For me, all I had to do was click the WAMP icon then click "Put Online", and it went online. It may be the case for someone else out there as well.
