QWebException: "argument of type 'NoneType' is not iterable" while evaluating
"'autofocus' if request.db not in databases else None"

Note that this is not the typical 404 page not found error. It's 500 internal server error.

Things I've tried :

- Clear cache

- Using --db filter

- Upgrade base, auth_signup, email_template module

Still the same..

Please help
