Well, I just uninstalled Firebird (a database server) because when I was starting EasyPHP it said that apache could not start because another program was using the port.
I uninstalled Firebird, restarted EasyPHP and it apache didnt throw any error...
Well, I will now try restarting my computer to see if that solves the problem...
And, I dont think I'm running any program that has its own webserver...
