[support] FCKeditor doesn't show up

Hi, Drupal newbie here :) I'm having trouble getting the FCKeditor to work on Drupal 6.5, FCK version is 2.6.3. I was able to activate the module and FCKeditor itself, set role permissions and put the FCK profiles right, following the README that came with the module. I even activated 'Full HTML'-filter. However, when I try to create content (just a page, to start out), Drupal only shows the standart text field. Also, 'edit-pages' is an 'Included' field in the relevant FCK profile. The global profile 'Excludes' an empty list, so that shouldn't be the problem I think. When creating content, there's no showing up of FCKeditor at all... Did I miss something? Where should I start debugging? Regards, Paul
