It could be something with cookies. Try to clear your cookies in your browser and test again. If you can login after that, try to disable all plugins and enable the default WordPress-theme and successive enable your plugins to isolate the problem.
Or it can be your .htaccess-file:
Follow these easy steps and you’ll get your WordPress Blog and Admin Access Back:
- Backup your .htaccess file on your hard drive
- Delete the .htaccess file from the root of your server
- Go to your blog’s admin panel and log-in
- On the left sidebar, go to Settings –> General and changes your
WordPress Address and Blog Address to include www (so it should be
http://www.domainname.com instead of http://domainname.com). - Save Settings
- Take your .htaccess backup and reupload it to the root of your
server
