Do you have Skype installed? It’s a known issue that if Skype was installed before XAMPP it will occupy port 80 which is the port that XAMPP needs to communicate with your Internet connection. There’s an easy fix for this problem.
Solution : Open up Skype and go to Tools and select Options. From the list that appears select Advanced and then Connection. There will probably be a check mark inside where it says “Use port 80 and 443 as alternatives for incoming connections” just unchecked that box and save your changes.
