I installed CKEditor as described. I've installed ebrahim-redmine_ckeditor-caea3058516c.zip into the latest redmine release (i've done a apt-get install redmine). After that, I am indeed able to select CKEditor from the Administration->Settings.
However, now when eg editing the Wiki I don't get any formatting buttons whatsoever, just the plain text box. I tried with both Google Chrome and Firefox to no avail..
Any ideas what can be the matter why CKEditor doesnt show at all?
