I get an error when I try to post the first question in my askbot site

edit

Hi, I've just installed a new askbot website. I was testing it and tried to post a question, I got the following error:

DoesNotExist at /questions/ask/

Group matching query does not exist.

Request Method: POST Request URL: http://naosabepergunta.herokuapp.com/questions/ask/ Django Version: 1.4.3 Exception Type: DoesNotExist Exception Value:

This website is new (it has no questions). I may help knowing that searching also fails, I get this error:

can someone help help?

ps: the posting question error happens only when I use the administrator user. When I create a new user, I am able to post questions normally. The search error keeps happening.
