I recently activated Arconix FAQ. Created a few groups and FAQs and created a page with ONLY the [faq] shortcode.
When I go to this page on the frontend, the page is completely blank.
Previously, I was using Easy Content Types from http://pippinsplugins.com to create a FAQ section, but I came across your plugin and decided to give it a try because I didn't want to go through creating all the templates required with ECT.
Before starting, I deleted the FAQ custom post type, taxonomies and templates that were created automatically with ECT.
I then activated AFAQ and all the previous FAQ items I had created were recognized by AFAQ. I created "Groups" and assigned each FAQ to a group. I then created a "Frequently Asked Questions" page and added the [faq] shortcode.
I should also note that I still use ECT for other custom post types.
