What is wrong with this code?

Hello Ben,

This is the most helpful plugin for listing authors I saw. However, I am having problem with it.

The plugin worked for me in one page properly where I listed the editorial team, see here:
https://arabic.alshahid.net/editoria

But again when i tried to list another group of authors as whose who contributed with articles to the site, it is not working, The page only shows the title and nothing else! even if there is any other text not related to the plugin it is omitted. The code I am trying to put is here please see if there is anything wrong:

[authoravatars order=post_count roles=administrator,editor,author,contributor hiddenusers=abdullahi_new,ahednaser,aljazeera,bbcsite,investigation,rueters,special show_postcount=true min_post_count=1 avatar_size=100 show_name=true show_biography=true]
