Hey

I would like to update the editor used in the CMS I use (phpwcms) from v. 1.5 to version 2 RC1 - but I have tried without succes . Now I hope you can help.

The old one was call in the template file via this code:

//////////////////START
//load FCKeditor
case 2: include(PHPWCMS_ROOT."/include/inc_lib/fckeditor.editor.inc.php") ;
$oFCKeditor = new FCKeditor ;
$oFCKeditor->ToolbarSet = 'phpwcms' ;
$oFCKeditor->Value = $content["text"] ;
$oFCKeditor->CreateFCKeditor( 'ctext', '100%', '500' ) ;
break;
//////////////////END



//////////////////START
/////////fckeditor.editor.inc.php looked like this:

<?php
/*
*the FCKEDITOR copyright DATA here

// The editor base path
// You have to update it with you web site configuration
