WordPress on Heroku and localhost with different databases: Can’t log in to Heroku WP dashboard

As the (long) title suggest, I have a WordPress blog that is running on localhost for development and Heroku for production. I modified the wp-config file so that when the site is on localhost, it pulls a local database and on Heroku it pulls a Xeround database.

I can log in just fine on localhost, but I can’t on the Heroku version.

When I go to http://myappname.herokuapp.com/wp-login.php and I enter information, it just refreshes the page.

Oddly, when I go to http://myappname.herokuapp.com/wp-admin it auto-redirects to http://myappname.herokuapp.com/wp-login.php?redirect_to=http%3A%2F%2Fmyappname.herokuapp.com%2Fwp-admin%2F&reauth=1 and after entering information it redirects to the login screen im stuck on above.

I have tried:

• setting the WP_HOME and WP_SITEURL options in my wp-config.
• setting the above fields in my respective databases
• messing with the .htaccess file

Any help in this matter would be greatly appreciated! I can not get this figured out!
