tinymce did not load in mailbox

hi all,

tinymce did not load in compose new mail to another member and it cause send botton did not work.

how can i remove tinymce from mail compose page or how can i solve this problem?

xsl was inabled in my server.

i have this js error  :

Error: tinyMCE is not defined
Source File: http://******/inc/js/mail_box.js
Line: 217

line 217 is :

var sComposeMessage	=  $.trim(ed.getContent());

and all function is :

// collect the `post` data ;
			var sComposeMessage	=  $.trim(ed.getContent());
            if(!sComposeMessage) {
                sErrorMessage = _t('_Mailbox description empty');
            }

			var sComposeSubject =  $.trim($('#' + htmlSelectors[1]).attr('value'));
            if(!sComposeSubject) {
                sErrorMessage = _t('_Mailbox title empty');
            }

			var sRecipientNick  =  $.trim($('#' + htmlSelectors[8]).attr('value'));

 first thing i would ask is how you removed tinymce functions? this appears to be where the first issue is stemming from? 

var sComposeMessage	=  $.trim(ed.getContent());

// collect the `post` data ;
			var sComposeMessage	=  $.trim(ed.getContent());
            if(!sComposeMessage) {
                sErrorMessage = _t('_Mailbox description empty');
            }

			var sComposeSubject =  $.trim($('#' + htmlSelectors[1]).attr('value'));
            if(!sComposeSubject) {
                sErrorMessage = _t('_Mailbox title empty');
            }

			var sRecipientNick  =  $.trim($('#' + htmlSelectors[8]).attr('value'));

i do nothing.

in compose page tinymec did not load and cause this problem and user can not send message.
