Hi
If the activities are not showing, this can be issue of wrong configuration in your Twitter application.
Kindly open the Twitter application and make sure you have added Website URL and callback URL correctly..
In callback URL add index.php at the end of site domain.
Example : http://prntscr.com/pyc0sz and give read and write permission http://prntscr.com/pyc0w8
Copy the Consumer API and Access Token and add it.
If your site still not showing this, Kindly submit your twitter dev login and site login details in Edit fields first post.
About the Documentation, I will update it very soon with new Twitter interface screenshots.
Regards
