Apache is not running from XAMPP Control Panel(ERROR : apache shutdown unexpectedly).This may be due to a blocked port.

Cause :

By Defualt XAMPP server use port 80.If this port used by another application in your system than apache server can't access this port and shutdown automatically.

Solution :

Go directory C:\xampp\apache\conf\ and open file httpd.conf. Scroll your file and search ServerName localhost:80 Now you need to change this port number ServerName localhost:8080

Now you can run your xampp apache server.i hope your issue resolved.
