I installed the CKEditor in Drupal 7, following the steps in the documentation. I set up the right permissions and the text options and I cleared the caches, but when I want to add or edit some content, I have only the plain textarea.

However, when I navigate to *Administration » Configuration » Content authoring » CKEditor*. and edit the Filtered and Full HTML, the WYSIWYG editor shows up as it should when I expand the *Editor Appearence* tab, so I assume it's well installed.

Anyone has an idea, a solution? Is it something I miss here?<br> 
Thanks a lot for your help.
