Thread:Project:Support desk/FCK Editor Issues

Hi, I am receiving the following error message whenever I try to edit an article: Warning: Parameter 1 FCKeditor_MediaWiki:: onCustomEditor expected to be a reference value given in (home directory)/public_html/(name of wiki)/includes/Hooks.php on line 117 Could you please tell me how to fix this or how to change to a different wysiwyg editor (e.g. tinyMCE)? Thank you!
