If you’re seeing this error it’s because FacetWP can’t find a suitable query. This usually happens when you have a custom WP_Query on a standard WordPress page. To let FacetWP detect the custom query, you have to add facetwp => true to the query arguments. See this section for more information.

This error can also happen if you are using the WP External Links plugin, or, if you are hosting your site on WP Engine, by WP Engine caching FacetWP’s API URL or by WP Engine’s object cache.
