Please upgrade to 2.2 here.

Categories API not working
Client wants forum info embedded in their site, /discussions.xml works as expected but /categories.xml returns this:
<?xml version="1.0" encoding="utf-8"?>
The documentation doesn't say anything about why this wouldn't work - the categories appear on the forum itself. I've tried deleting the cache ini files but am at a loss for why this isn't working.
Using the latest build 18.104.22.168 (upgraded a previous version). Anyone know why this is happening?
