Problem with showing BBpress in Upfront theme Parrot

I have problems with showing BBpress forums when I'm using Upfront theme with Parrot.
Im able to see my forum index, but on that page I'm also using shortcode for that.
When I try open a forum next page, just show the forum title and then rest of the page is white. Cannot submit new questions or anything else.
When i try edit the page with edit page using Upfront and then place shortcode, then this is just showing up on site, still no forum is showed or anything else.

No problems when i try activate default wordpress theme.

Can anyone tell me how i can get BBpress working together with Upfront?
