Hi,
If what you require for TinyMCE is just CSS based then you can add that as an editor.css and add it to your Roshni theme style directory. Then ensure that the editor sheet is set in the roshni/config.php
$THEMES->editor_ sheets = array('editor');
That should ensure that it displays as it should In the editor.
If it is not then it could be a problem with the dos I theme, in which case you need to add the missing CSS to the theme itself.
Hope this helps?
Mary
