I have a Windows VPS and I tried all major php/mysql/apache packages on it (WAMP, XAMP, easyphp) but it gives me error "Port 80/21 is already in use by the system". How to fix it?
Umm you might need to stop IIS I'm not very familiar with VPS hosting since I generally use dedicated. I would almost bet that IIS is on in services just turn it off.
