I recently installed the older version 2.5 of WAMP Server for the local WordPress development and found out an issue.

Once I tried to access my local WordPress installation by clicking on the link under My Projects section, It gave me an error.

This site can’t be reached.

because http://localhost was missing in the address.

I quickly found a solution at stackoverflow WordPress section.

You just need to change this line: suppress_localhost = true; to $suppress_localhost = false; in wamp/www/index.php file.

Watch the video to learn how to fix this issue.
