Wamp Port 80

[Strupantwn]

hey, I am trying to get my account creation page up and running and it works

when I got to localhost.com but when I try and go to my dyndns, it wont work.

im using spora and all the configs are double checked and correct,

when I try test port 80 option , it gives me this error

Your port 80 is actually used by :

Server: Apache/2.2.8 <Win32> PHP/5.2.6


Press Enter to exit . . .

where can I find this port that is being use? so i can close it ?
