I am getting following console logs:
1:14:33 PM [apache] Possible problem detected!
1:14:33 PM [apache] Port 80 in use by \"c:\\program files (x86)\
Please update your post with output of the following command, don't forget to correct the path :
C:\> path\to\xampp\apache\bin\httpd.exe
I think now its not the port conflict issue as you have changed the port.
By the way you can change the settings in skype for not using port 80 and 443, in new version there should be some changes but you should be able to find it. :)
