Hi, I have installed this in my sidebar. I wanted to filter out a bunch of Media library categories, and only show blog post categories. But I can only get this widget to display ALL the categories.
When I type in the ID numbers of the media categories into the 'Hide Categories' box, and click save, then ALL the categories disappear from my sidebar.
Tried typing a '1' into the 'Hide Empty Categories' box to see if that would filter out the non-blog categories, but that didn't work either.
Hopefully you can suggest what might be going wrong, or I'll have no option but to delete the widget, as it doesn't function for me.
