Illegal string offset && Uninitialized string offset: 0

What are you using the version of wordpress?

wordpress 4.0
bbpress new UI 2.3.1

Where and when you can get this error? When you try to activate the plugin? Where else?
It is desirable to attach a screenshot.

I get the error when I sve without checking the box.
IMG1
IMG2

When I do check the box and save I get error Illegal string offset ‘checkbox’ on line 66 in the admin and on the line 16 on the frontend

How I can to contact with you?
