This is a very strange issue, and it never happened before to me.
In Configuration -> My Store the HTML editor is set to FCK.
I have uncommented lines in admin/includes/init_includes/overrides/init_html_editor.php
I have also set this file to 777, in case this is a permission issue.
But when I go to edit a product the editor is not showing.
In fact no editor is showing: I have also tried TinyMCE and HtmlArea.
It is like no editor is installed but all are.
