Can’t create new questions in the frontend

Hi!

I have installed your plugin in a WordPress 4.0.

After enable it, I try to publish a new question on the frontend with the ask form. When I submitted the form, it remains in the same page with the form empty and it doesn’t create the question.

I can create the questions in the WordPress dashboard, but in the frontend I can’t vote or answer them too.

What could be the problem?

Thanks in advance

Regards, Daniel Moreno
