I recently migrated to a new server and a new install of WordPress. We installed the plugin, but our imported FlipBook doesn't show either in the front end or the preview.
I've checked to make sure our license is active and created test books with minimal content, but I can't get any book to show up.
Did you change your domain name?
No, the domain is the same. I've made sure that the license is active on the new install under the same domain as before. The "License" box shows my domain name correctly and says "Deactivate" -- so it's pretty clear it's active. The preview shows nothing on the page and the shortcode doesn't display anything. I've tested with several types of books.
