WordPress Admin Redirect Problem

My site is hosted through GoDaddy. Apparently there was just an update done to wordpress. I bought a template and uploaded it to my site. Now when I go to login at http://www.mysite.com/wp-admin, it redirects me to http://www.mysite.com/wp-login.php?redirect_to=http%3A%2F%2Fb-modern.com%2Fwp-admin%2F&reauth=1. Then I enter my user name and password, click login and clears the user name and password and redirects me to http://www.mysite.com/wp-login.php

After that i enter the user name and password again and nothing happens. It just clears the name and password. GoDaddy has no knowledge of what is going on and i have cleared my cookies multiple times, didn’t help.

I’m new to this so if anyone has any suggestions, I would be very greatful.
