FAQ tabs are not expand while click on it

Hi Support Team,

1. Tabs are not opening
I am trying to use your support Plugin and added some FAQ's but I think there is a problem related to my geotheme theme in use. I cannot open the questions on my tabs. While clicking on "+" they are not open.

2. How to enable access to faq all users without force them to log in?

Could you please give advice how to enable that?

Regards, Alex
