Well it's the same deal as the other mods that had to fix this, functions_wysiwyg.php was depreciated in vb 4.1.4, and is no longer distributed with vb files.

To work correctly it should be making use of the new ckeditor.php

EDIT: Looking at the 4.2.7 xml, it's still making use of the old editor, and I'm guessing people that claimed it working still have the depreciated files on their server:

Removed Files:
clientscript/cms_textedit.js
includes/class_editor_override.php
includes/functions_wysiwyg.php
packages/vbcms/bbcodehelper
packages/vbcms/bbcode/wysiwyg.php
packages/vbcms/controller/editor.php
packages/vbcms/editor
packages/vbcms/route/editor.php
packages/vbcms/wysiwyghtmlparser.php

and those that do not have it working are either on a new install or removed the depreciated files, as far as I can tell Easy Forms 4.2.7 does not make use of the ckeditor
