Hi Daniel

Have you checked out the docs?

I see you are using the shortcode display method – which is covered here:

http://www.designsandcode.com/documentation/search-filter-pro/getting-started/creating-your-first-search-form/

Ensure to have the results shortcode somewhere as well as the “Results URL” step (in the “display results” tab).

If you’ve done all that, I think it could be possible there is a conflict in the “Tags, Categories & Taxonomies” tab – just as a test, try clearing all these out and see if some results show up?

Thanks
