Admin Panel Logon Failure (Please Help)

Hi there,

I shifted my hosting before it I took complete backup.

At the new hosting, I uploaded all the files and imported the database.

Now when I try to log on http:www.sitename.com/wp-admin it don’t accept my user id and password.

Can anyone tell me plz how to resolve this issue.

Any help will be highly appreciated.
