Cannot type in text-boxes

Here is my plugin list: https://imgur.com/a/ufYcXbr
Theme: http://clapat.ro/themes/clapat-blog/

Cf7 works on site as you can see on: http://www.mediastyle.at/fumee/index.php/kontakt

But when I start it via lightbox modal (VCkit plugin): http://www.mediastyle.at/fumee/index.php/cosmetics#berater it doesn´t work. Thats strange because I use it on other sites (other theme) and lightbox with cf7 works fine: http://www.alexanderkoch.at/jausenbox/#fitness

Hoping for your reply.
