Description:
When testing the tag <categorytree mode="pages">Foo</categorytree>,I get the following error:

Fatal error: Call to undefined function: validatetagattributes() in .../extensions/CategoryTree/CategoryTree.php on line 226

All files for the extension have been installed, and the permissions are correct.

I have
$wgUseAjax = true;
require_once("extensions/CategoryTree/CategoryTree.php");

Is there anything obvious I missed?

Version: unspecified
Severity: normal
