I had few databases related to different projects in the WAMP. I don\'t know what happened, Today, when I go to PhpMyAdmin, I was just able to see the default databases and rest
Have you checked my.ini file? Just find datadir it should refer to db folder (e.g datadir=D:/Wamp/bin/mysql/mysql5.1.30/data) - goodluck :)
my.ini
datadir
datadir=D:/Wamp/bin/mysql/mysql5.1.30/data
