Hi,
The search results page in wordpress is specifically built to only display post type results. The plugin tries to “hack” those other results by sending fake posts with a modified url and titles as a placeholder.
You have two options:
1. To not display those results there using a custom code snippet. If it is okay to ignore them on the result page, then I can provide a small custom code snippet to exclude them when the results are directed to the search results page. Let me know if you need that.
2. To use the theme functions to modify the search.php file to fetch the fields from the live search (such as the images) on the results page. This requires custom coding though, so I only recommend doing that if you are comfortable with theme editing. These may or may not work, highly depends on how the search results page is built so I can’t guarantee anything.
