I've got a problem with the Ask A Question module.

If I leave in the option to check to see if a guest is allowed to post, people not logged in can post a question, but customers logged in can't. Also, if I remove the checking for that because it's not setup to use it, I can get it to redirect to the login page, but customers who are logged in still can't post a question. A blank page loads instead of the form.

Any ideas what's wrong?

Thanks!
