403 Forbidden cannot access PHPmyadmin on localhost

to solve the problem just go to 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 
</Directory> 

You can set them to allow connections from all IP addresses like follows :

change
Order Deny,Allow 
Deny from all 
into
Order allow,deny 
Allow from all
