is_authenticated() raises TypeError TypeError: 'bool' object is not callable [duplicate]

Answer 1

From Flask-Login 0.3.0 (released on September 10th, 2015) changes:

• BREAKING: The is_authenticated, is_active, and is_anonymous members of the user class are now properties, not methods. Applications should update their user classes accordingly.

So you need to change your user class and code accordingly.
