Thumbnail Images Not Showing

Hello Dave, I apologize if this question has already been asked, but based on the research I’ve done I haven’t seen a response to this question.

When I first installed this plugin I had only 2 custom post types that would show up in the search with thumbnails. The rest showed up, but no image. Those post are now deleted and therefor no post thumbnails show up at all.
I cant remember doing any mods that may have interfered with your plugin.
Its strange because unchecking and checking other fields like ‘excerpt length’ and ‘show veiw more results’ will change the search appearance but whether or not ‘display thumbnails’ is checked, no image shows up on search.
I’ve even tried disabling all other plugins. Could this be a JS conflict?
This is such a fantastic plugin that even if I cant get this to work, no biggie. Its just puzzling me why this would occur.
If you have heard of this before and have any input to help I would really appreciate it.
Thanks
