I've just installed the plugin and it's not working at all.

Hi,
I've just installed the plugin and it's not working at all. After installing it the plugin a error message that I don't know how to resolve. Please see attached.

I'm not pretty sure how the plugin works, but after installing it, I think it should have created a page for question automatically, but I can't see anything. Even when I create a question in the the WordPress Dashboard I'm not able to see it.

I hope you can fix it.

Regards,
Manuel
