Category list on Multisite

Hi,

I’m working on a Multisite installation of wordpress, and I’m setting up the events manager plugin on one of the network sub-site (not the main blog) with global tables active to share events accross the network.

On this sub-site, I want to display the events category list and hide empty categories.

I tried through shortcode option :

[categories_list hide_empty=1 limit=50]#_CATEGORYNAME[/categories_list]

And through php function :

<?php if (class_exists(‘EM_Events’)) {
echo EM_Categories::output( array(‘orderby’=>’name’,’hide_empty’ => true) );
}?>

But when hide_empty option is on, it never displays any cats whereas events matchs existing cats.

How can I achieve this ?

Thans by advance for your time and answer
