You don't have permission to access /phpmyadmin/ on this server (WAMP)
This is the message I got when I tried to access phpmyadmin after reinstalling WAMP server to a newer version. After some searching I was able to find the problem.
When you uninstall your previous WAMP server there will be still few files that will be left not deleted and will not be replaced by the new install. One such file is the phpmyadmin.conf file that is under C:\wamp\alias folder. This file holds the actual path to the phpmyadmin folder inside WAMP.
If the new WAMP server has a new phpmyadmin version this phpmyadmin.conf will still point to the old folder which is not existing inside WAMP.
goto C:\wamp\alias\ and edit the phpmyadmin.conf file using notepad
Alias /phpmyadmin "c:/wamp/apps/phpmyadmin2.11.6/"
# to give access to phpmyadmin from outside
