Error: Invalid “list” parameter.
Possible values are: “series”, “preachers”, “topics” and “books”.
You entered: “”

Shortcode looks like:

[sermon_images tax=”wpfc_sermon_series” order=”DESC” orderby=”id” size=”sermon_large”]

I dont know the plugin, researched the error but not seeing a resolution, seems possibly related to 4.7.4 upgrade but not sure what client was doing before this happened, they have a ticket open with us on this.
