I'm getting a TypeError: 'bool' object is not callable, for {% if current_user.is_authenticated() %}

I took off the () for is_authenticated, and the {{ current_user.username }} is still not displaying

SOLUTION!

Just remove parenthesis from authenticated. DONE

It should be " {{ if current_user.is_authenticated }}"

From Flask-Login version 0.3.0 and up all the following methods: is_authenticated() is_active() is_anonymous()

has been changed to properties, which should be called without the parenthesis '()'
