Could anyone shed some light on this error im getting, i dont have any webserver running.

Code:

---

evilgrade(notepadplus)>start
evilgrade(notepadplus)>

Error: [WEBSERVER] - Cant't create a listening socket: IO::Socket::INET: Address already in use

---

what ever port evilgrade is trying to use is already being used, "address is already in use",
