No Editor in Frontend - Checked all documented Solutions

Hey Guys,

my Editor is not showing in Frontend. Even in Backend it works fine in every Textformat. I checked all Solutions i've found for this Problem. Maybe it is an issue, caused by my own Template? I got no Special Template for Commentform itself (its the only form which is shown in frontend, so it is the only one without wysiwyg - but i Need it for comments), but maybe i forgot a class or something like that in html.tpl.php or Body.tpl.php, which ckeditor Needs to select the Input fields? I got no idea! Maybe someone else got the same Problem? I tried another Editor - Same Problem.
