Please upgrade to 2.3 here.
The 2.2 and earlier branches are no longer being updated.
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 22.214.171.124 (upgraded a previous version). Anyone know why this is happening?
