I have changed the port Apache is listening to, to port 8081. and I have forwarded that port in my firewall. But when I try to go to the wiki www.sadlynotworkingwiki.com:8081 I get the following error:
The requested URL / was not found on this server.
Apache/2.2.4 (Ubuntu) PHP/5.2.3-1ubuntu6.3 Server at www.sadlynotworkingwiki.com Port 8081
Note I am a noob.
