[ultimatemember_wall] shortode

Hi,
I’m trying to use the [ultimatemember_wall] shortcode, pasting it on “User” page, right under [ultimatemember form_id=xxxx] shortcode (which is showing the profile of the user).

[ultimatemember_wall] shortcode isn’t working, i see [ultimatemember_wall] written a a text on the page. If I try to add a parameter user_id=”xx”, notginf changes.

I took this shortcode from your documentation page.

What I’m doing wrong?
