Thread:Extension talk:WYSIWYG/No textbox, everything else is fine

No problems using older versions of WYSIWYG but I tried 1.6.0_18 just to fix the images issue and I can't get it work fine. Toolbar looks fine and no PHP errors messages. Just a grey box on the text area.

I am using:
 * MediaWiki: 1.16.4
 * PHP: 5.3.8
 * MySQL: 5.5.11
 * WYSIWYG extension (Versión 1.6.0_18 [B56], CKEditor 3.6 (revision 6902))

Javascript console reports: mw.config is undefined extensions/WYSIWYG/ckeditor/ckeditor.js Line: 148 Thanks!
