Possible solutions:

1. Open your core_config_data table in phpMyAdmin and make sure you have changed the URLs if not than change web/unsecure/base_url and web/secure/base_url with your appropriate domain url (trailing slash necessary) like http://www.example.com/
2. Incorrect permissions on var/session , preventing session files from being saved. So set 0777 permissions to var folder.

3. The cookie domain in

   System -> Configuration -> Web -> Session Cookie Management

   doesn't match the actual site domain

4. Clear contents from var/cache, var/session directories after changing base_urls through ftp
