AnswerBox is an starter theme, this mean you can use it as a base when creating your AnsPress+BuddyPress theme, hence no option page for AnswerBox.
Its such simple to setup, so hard to explain. 🙂
Everything is ready to use in this theme, just drop widgets and it will look like the screenshot.
Thought, if you need more assistance with setup, drop an email to [email protected] with team viewer ID and Pass. Team viewer support is available between 9AM – 3PM (GMT 5.30)
