Another thing we detected with the Avada theme: sometimes people changed the internal theme settings and still think the website Search works wrong because of WPFTS issues.
Well, in the Avada theme there is a Search settings (you can navigate there by Main Menu > Avada > Theme Options > Search Page). There are two options that you should care about: "Search Results Content" and "Search Results Excerpt".
These options are not conflicting with WPFTS Pro, however, if you disable the Excerpt, it will not be shown on the Search Results page.
Also, if you disable a specific post type in "Search Results Content", it will be not shown too.
We would propose to set them to "On" and "All Post Types and Pages" respectively. Please see another screenshot:
Hope this will help you to avoid some issues with WPFTS Pro and Avada theme.
