How to use CKEditor on the front-end? CKEditor do not work on one specific theme, it works fine in the back-end and also when I switch the theme.

When I look the sources, I get the JS &amp; CSS, ckeditor class on textarea but not the injected code that CKE add under each textbox with id="cke_edit-body".

What can be the sources of the problem?

I know it's not jQuery, I found similar issues but they were provoked by a custom jQuery update, I use 1.3.2
On Input filter option (admin/settings/filters) you can check the user permission for each type of input filter you have on the site.

Then if you are using the WYSIWYG module, at admin/settings/wysiwyg you can check which type of editor is using each input filter.

If the WYSIWYG editor is working for anonymous user on one theme but not on the other, you could also check (with Firebug or Chrome DevTools) if there are Javascript errors. If that is the case, please, update this post with the error message.
