Comments.Text: Yeah it's in the right spot, I just meant my craft folder on the server. So it's still config/redactor, just inside of the overall craft folder.

Comments.Text: Weird that the error msg is `Unable to find component class 'Redactorl'.` and not `Unable to find component class 'Redactor'.` What is 'l' doing there? Is there a typo somewhere?

Comments.Text: Hmm I think I figured out what went wrong. In the admin page settings, the field types were set to plain text and I got the same missing component class 'RedactorI'.
  But I set the field type to Redactor and now my body and the rich text editor are working.
