Translate label of Comment Body with String Override I'm using i18n and string overrides for translating fields in the front end. I opened up the comment-section for several content types and it's working great. The only thing is: I can't find a way to translate "Comment" to german to "Kommentar".

I just found out, that the Comment-Form doesn't get a specific language-tag. So it is und(efined) which leads to the english word Comment.

The easiest but a little dirty way to fix that is to translate it by hand with the hook_alter_form in the template.php

Is there a more cleaner way to do that?

Thanks
Yes there is you should try out
Localization client

This would help you out, and translate the content in t()
