If you have problem login to Drupal after some configuration changes or update, you can try the following steps:

• Try login using different browser, if you can login using another browser, likely a cookie problem.
• Clear the problem browser cookie of your site
• Try login again

If the above does not work, you can try edit sites/yoursite/settings.php

• specify the $base_url
• OR this fix to comment out the cookie section

Happy drupal-ing
