I wrote a small application for a social media site and I have a problem. I'm using {% if user.is_authenticated %} after I log in I'm getting the options in the navbar which should not be displayed for an authenticated user. The page keeps bouncing between two pages. I have made a video of the problem. Please have a look at it.
Video.
