Am unable to login to my joomla site al of the sudden despite having the right credentials. I have changed the password via my phpadmin but in Vain. I tested it with wrong/non existent logins and am able to get the error message that username/password are not valid. However when I use valid logins, the site just refreshes and brings back the login panel. I have cross checked my configuration file and all looks okay.
Some one please help out.
