Why my Facebook Feed widget doesn't update my profile picture?
Sometimes when you update your profile picture on Facebook, it doesn't update in your widget. This happens because of the way our widget interacts with Facebook.
When the widget makes a request to Facebook for the data, Facebook gives us only one profile picture - the oldest one in the profile picture folder in your Facebook account, and this is the picture that we display in the widget. This is regulated on Facebook side, and unfortunately, we cannot change this behavior.
To display your current picture, you need to remove the pictures you've used previously from the profile picture folder. This way the widget will get the new picture from Facebook and display it in the feed on your website.
