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.
