I just copied and pasted the whole drupal content folder from my server to my localhost and also I dumped the DB to my localhost, but now my admin user authentication credentials are not working in the localhost.
I even reset my admin password (UPDATE admin SET pass = MD5('newpassword') WHERE uid=1;)
Also in watchdog table I am having this message when I try to authenticate:
“Session opened for %name.”
Any ideas??
The error was parameter
$cookie_domainon file/sites/default/settings.php. it is working fine now
