When I start EasyPHP: “Apache Cannot be Run. Another web server is using the web port or port is blocked by firewall”…
1. By default the Apache port is set to 127.0.0.1:80, so make sure other applications like IIS, Skype, Yahoo! messenger and etc applications are not using the same port (port 80).
2. If the port already used by other application, change the port to 8080. How? Please read more from this post.
3. If the problem still exists, then try this: Press “Ctrl+E” and there is a pop-up window or go to Configuration>EasyPHP:
4. Uncheck the “Check Server’s TCP port before starting” and press “Apply”. Then Restart EasyPHP again.
