Hi Paul, you can use archive mode, then put in the filename: taxonomy-sermons-category.php
but see the notes in the above link about potential issues with archive mode, your template might have a custom query inside which is causing it to ignore the S&F query – so you will have to remove this.
If you are using results method, then you create results.php
in search-filter folder – but you msut also place the results shortcode into a page – the results shortcode then loads the results.php template where the shortcode is displayed – probably your results.php won’t be a full template (with the get_header() etc – see the sample results.php on how to do the loop) – you can get the results shortcode from the S&F edit screen.
Thanks
