Related Items Extended is blank

The module was originally working on my site but no longer does. It is assigned through Advanced Module Manager to show on all Single Article pages in the sidebar position:
www.kreolmagazine.com/features/we-rate-i...-rise-of-zoe-saldana
awesomescreenshot.com/05c1mqw0d0
No content displays and even the module title does not show even those it is set to.

The articles all have normal meta information:
<meta name="keywords" content="Zoe Saldana, Kreol Magazine, Creole, actors and musicians, Star Trek, Avatar, StarTrek Into Darkness, Avatar 2">
<meta name="description" content="The Meteoric Rise of Zoe Saldana">

The module is set to use the default layout and I have the plugin enabled.

Firebug shows no errors. Any help is appreciated.

Hello

I've take a look at the backend...and I tried by publishing Articles - Related Items which has similar function like RelatedITemsXtd also assigned it to sidebar-a position. but the problem is the same, this module also won't shows up at that page.
So I guess this is related with how the Advance Module Manager works which I don't know how.
So I think you better ask their support regarding this issue. It is indeed not the issue from our module itself, but the standart Joomla Related Items module also not showing up there.
