The login link in the top left appears to work as it goes to a page to enter the usernames and password, but it goes back to the logout screen after clicking the login button.
After logging out the link on the login in the top left becomes: http://metrobostondatacommon.org/accounts/login?next=/accounts/logout/
After logging out of the DataCommon, I can only log in again if I click the 'log in again' link. It goes to: http://metrobostondatacommon.org/accounts/login
