some issues with toggle form and reply and agree conditions - nothings happens when clicking

Hi there,

I can't figure out how to proceed further

when using toggle the form the form disappears but when clicking on the button nothing happens (it's linked to: javascript:void(0); ) same when clicking on conditions which I think should be shown then.

I also don't see any possibility to reply on comments although I enabled function in k2/layouts/comments

I also got doubled content there.

Please have a look at:

Thanks for your advice.
