WAMP says Forbidden You don't have permission to access /phpmyadmin/ on this server Windows 7 or 8
First of all locate "phpmyadmin.conf" file under "C:\wamp\alias\". My WAMP installation is in C drive.
Then edit that file with any editor you have. I am using Notepad++.
You will find
Options Indexes FollowSymLinks MultiViews
Deny from all
Allow from 127.0.0.1
Now change "Deny from all" to "Allow from all".
If you want you can remove "Allow from 127.0.0.1" or can keep it.
Now open left click on WAMP icon and restart all services. After it turns green, visit "http://localhost/phpmyadmin/". You will find your phpmyadmin working.
