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

Question

I have installed XAMPP (xampp-win32-1.8.2-0-VC9-installer.exe) on Windows 7 successfully. But unfortunately, the following error was found during running Apache from XAMPP C

Answer 1

1. Go in xampp/apache/conf/httpd.conf and open it.
In the httpd.conf file at line 176 Replace

ServerName localhost:80
with
ServerName localhost:81
It will work.

Or 2. Even if the above procedure doesn't work. Then in the same file (httpd.conf) at line 45 replace

   #Listen 0.0.0.0:80
   #Listen [::]:80
   Listen 80 

with

  #Listen 0.0.0.0:81
  #Listen [::]:81
  Listen 81
