[MediaWiki-l] Fwd: "cancel" link while editing a wiki page with WYSIWYG activated leads to a 404 (index dot php disapears from the url)

Hi, Hope my question will fit on this list. I just upgraded my Mediawiki to 1.20.4. I encountered problems with FCKeditor, and I had to install WYSIWYG extension instead. I also had a couple of problems after installing this extension: - Editing an article with this extension delete any category associated with the article: solved with http://www.mediawiki.org/wiki/** Extension_talk:WYSIWYG#Editor_**removes_assigned_category_**16286<http:/… - When activating or using the extension while editing a wiki page, the "Cancel" link at the bottom of the edit frame returns a 404 (the /index.php/ is not present in the url... Can't find any fix for this second issue, anybody has any useful suggestion? Thanks a lot. Regards. Jules Mediawiki: 1.20.4 PHP 5.3.2 MySQL 5.1.67 WYSIWYG extension (version 1.5.6_0 [B551], CKEditor 3.6 (revision 6902))
