Limit Categories or Similar?

I used to use the Limit Categories plugin when I used WordPress a couple of years ago, but now using it brings up the following error:

Fatal error: Call to undefined function get_nested_categories() in /path/to/themelady.com/wp-content/plugins/limitcats/limitcats.php on line 233

Can anyone recommend a similar plugin, or can someone tell me a way to fix this issue? The plugin limits the categories to which users of certain levels can post. Thank you.
