Comments Form not showing up

So I’m working on a new website and implementing inline comments. The comments are showing up, I can answer inline comments but I cant create new comments on an existing thread or on an new paragraph. My guess is, the function loadCommentForm() isn’t loading or not working. I’m also using buddypress so it might have to do with it even though I deactivated buddypress but it didn’t change anything. Do you have any idea, what the problem could be?
