login button gone on dev portal with bootstrap theme

Hi Apigee community,

I have switched to the bootstrap 3 theme for the developer portal, but now my login link in the navigation top right corner is gone. If I manually go to /user/login the login form is displayed inline in the content block, although before it was in a modal. Furthermore I do see the My Account and Logout buttons, so adding the user login menu to the navigation does not fix my issue.

Anyone know where to look and how to fix?

Kind regards!
