The post type has changed inexplicably, and there was no attempt to move over the data by the plugin author.
I was able to restore my FAQ by running this query:
UPDATE wp_posts
SET post_type = ‘wp_faq’
WHERE post_type = ‘faq-item’;
I also had to changed the short code to this:
[wp_faq]
Everything was in the same group so I was OK after that although I lost my styling because of course the HTML/classes changed.
Absolutely careless upgrade with no improvement that I can see!
