Just go to your Wamp Directory insder “c:/wamp/alias/phpmyadmin.conf” — This path.
Here you can check this <Directory “c:/wamp/apps/phpmyadmin3.4.5/”> the phpmyadmin version is same in your c:/wamp/apps/
Then you see this file
1. AllowOverride All
2. “Deny from all” to “Allow from all”
3. “Order Deny,Allow” to “Order Allow,Deny”
that is all. Now its working. If this is not working then you go to check your ISS part.
