I was using Wamp server on my Windows 7 pc behind me. It was working fine. I then installed Windows 10, Wamp started but was orange and could not start apache. I then reinstalled the latest Wamp in the hope to fix it however now it gives me an error when I try to launch it:
The configuration file contains an error on line 325: [EParseError] Parameter "Service" specifies an unknown server.
I can use Xampp but I have gotten used to Wamp so if someone knows how to fix this I would greatly appreciate it.
So it turns out that Windows 10 uses port 80 by default. Forgetting that wamp is really badly written and can't install over itself you need to simply change the port it is running on. Hope it helps anyone else having this problem.
