I am glad to hear that we were able to get your login working! From the entries in your database tables, the users seem to be being saved correctly. There are a couple approaches we can take to tracking down the problem now.
1. When you log in with your @tvsd.us account, do you see Google Cards on your page, such as Drive, Calendar, Apps, etc? Also on the profile page, do you see a set of standard streams to opt into?
2. Do you have access to your error logs? If so, check and see if you see any php fatal errors.
I suspect your issues are either coming from a missing database table that wasn’t installed, or a server configuration issue.
I look forward to hearing back from you and resolving these issues.
