Can't access the login screen [locked-out]

[gustavovalverde]

After updating, now I can't access the login screen, so It's not possible to log in into the instance. We're getting an error from this line:

request.params['title'] = root_user.company_id and root_user.company_id.name or 'xubi.me'

This is the log:

Sorry for the inconvenience. Please remove that line in your code first. I will update new code shortly
