Changing Apache port to 8080

C:\xampp\apache\conf\httpd.conf:

• Search for “Listen 80″, change to “Listen 8080″
• Search for “ServerName localhost:80″, change to “ServerName localhost:8080″

C:\xampp\apache\conf\extra\httpd-ssl.conf

• Search for “Listen 443″, change to “Listen 4499″
• Search for “<VirtualHost _default_:443>”, change to “<VirtualHost _default_:4499>”
• Search for “ServerName localhost:443″, change to “ServerName localhost:4499″

Then, you should be able to start Apache successfully through the XAMPP control panel.
