Site Categories not being displayed on my page

Hello support,

I am using the Site Categories plugin on one of my sites, and I'm unable to see the list of categories from the select page, which a created to display the categories.

Link:

I have made sure to select "No", for 'hide empty categories', however I'm still not able to see any categories, lists etc.

Could be some conflict with the theme I'm using, and the pages aren't showing any of the category plugin features.

Any help on how I can display the categories lists on my page would be great.

If you need any further information please don't hesitate to ask.

Thanks again!
