We fail to get CategoryTree to work with mw 1.20 and see no documentation that a specific older version should be used. Failing: http://biowikifarm.net/test_v20/Category_Test - this should look like http://biowikifarm.net/test/Category_Test (the latter still under 1.18.x) See here for other installed extensions: http://biowikifarm.net/test_v20/Special:Version This seems to be related to the discussion http://www.mediawiki.org/wiki/Extension_talk:CategoryTree#no_categories.21_20941 where others seem to have similar problems with mediawiki version later than 1.18.
For an example on a WMF wiki, see https://meta.wikimedia.org/wiki/Grants:Index/Requests (if you do see categories, purge, and they'll disappear).
Investigating now
This may be a simple matter of reverting Gerrit change #34493 and Gerrit change #36750 . Since these were both Reedy's change, and since that's the only thing that changed in CategoryTree, that seems like a good place to start.
I think it's much more likely just to be boolean fail: -» » if ( $title === null || $title === '' || $title === false ) { 878 +» » if ( strval( $title ) !== '' ) {
