Hi,
I am experiencing the same issue.
I am running a Virtual Box fresh Ubuntu 14.04 server. The box was created a few days ago on Hashicorp, so I'm assuming it should be updated, but I'm not certain as to whether Hashicorp includes the updated packages in the boxes. Anyways, after booting into the server, I ran the Taigo setup script and it ran successfully. When I direct my Host browser to the IP Address of the Guest, I get to the Taigo login. When I click sign up, the registration page appears, however, after I enter in my credentials and click register, nothing happens. Admin and 123123 doesn't work either.
Please help! I really want to use this software!
