Hi,
I am a new user of wamp server. I have installed the latest version of wampserver (32 bit) on my pc (vista).

The problem is when i start [localhost]. it is showing 502 Unknown Host.
I don't know how to get rid of this problem. and it is also showing red icon in the task bar which should be brown.

so, please look into the matter.
thank you,

Make sure no other program conflict Wamp such as IIS, Microsoft Web Deploy, SQL, Skype, Zonealarm, firewall/antivirus, NOD32, Eset, any web related program including Remote Desktop, Teamviewer or Apache, MySQL, PHP outside wamp folder (ie. in Program Files or System32 folder) ...

IIS and Apache/Wamp are both web server and might conflict in some way, so you have to disable IIS in order for Wamp to work

Disable IIS in Vista/W7:

Control Panel, Uninstall Programs, Turn Widows Features On or Off, uncheck Internet Information Services

Disable IIS in XP:

Control Panel, Add/Remove Programs, Add/Remove Windows Components, uncheck Internet Information Services (IIS)

Restart computer, then restart Wamp

Also, in folder C:\WINDOWS\System32\drivers\etc, open file hosts and delete anything in this file and have only this line below and nothing else

127.0.0.1 localhost

If using Skype, open Skype > Tools > Options > Advanced > Connection then uncheck "use port 80..." restart Wamp then Skype

Have fun,

Hello,

I was trying to fix the errors as listed by you but nothing is working in this case.
I've disabled IIS, uninstalled antiviruses, skype , changed firewall settings etc..

Also re-installed the software but the same error message is displayed upon execution of the software i.e. "502 Unknown host".

please help me..
