Another thing I found out is that if your network adapter uses IPV6, it will not show as 127.0.0.1 but ::1
What I ended up doing is this:
<Directory "c:/wamp/www/">
Options Indexes FollowSymLinks
AllowOverride all
Order Deny,Allow
Deny from all
Allow from 127.0.0.1
Allow from ::1
</Directory>
The same goes for your PHPMyAdmin access, the config file is phpmyadmin.conf :
<Directory "c:/wamp/apps/phpmyadmin3.4.5/">
Options Indexes FollowSymLinks MultiViews
AllowOverride all
Order Deny,Allow
Deny from all
Allow from 127.0.0.1
Allow from ::1
</Directory>
