Hi,
I created a forum, his id is 3569159-2 and it contains one topic.

in this page of my website http://radiotounsi.com/?page_id=4862
I tried to display this forum by using the shortcode [bbp-single-forum id=$3569159-2] but nothing is displayed, but other bbpress shortcodes work just fine like [bbp-forum-index] and [bbp-login]
I switched the theme to twenty sixteen for testing purpose, same problem

The correct code would be

[bbp-single-forum id='3569159-2']

but I suspect ‘3569159-2’ is the url not the post ID as post ID are a whole number and what you want

so go to

Dashboard>forums and select all forums

If you hover of ‘edit’ of then forum you want, you’ll see at the bottom left of the screen

url…post.php?post=12345&action=edit

it is the 12345 that you want to put in the shortcode

Robin might be on to something with the url thing. Robins suggestion works fine, but I usually suggest looking into using the Reveal IDs plugin, as it really makes it easier by just adding a column in posts like Forums > All Forums list and users list in the WordPress backend.

Thanks Robin your suggestion was the true one, that was really tricky to find out.
