Internal server error/login problem

Hellow Folks,

I was upgrading to Version ERPNEXT12. First i got an Internal Server Error but after I ran the below commands its disappeared:
bench --site all migrate
bench update --reset

The current issue is that I can not log in to the site; there is no where that I can key in the login credentials. Below is an error from my frappe-bench/logs.
