I am having the same issue… is there any further info on why this could be happening?
Thanks for replying Andrew. “Custom” taxonomies probably wasn’t the way to phrase it, I simply mean taxonomies that I would create.
So, for example if there were a custom post type of “Cars” there may be different taxonomies such as “Price” “Model” or “Color”. I am looking for a similar functionality of the FACETED SEARCH plugin above (cheers to you on developing the plugin) that uses taxonomies instead of categories or tags.
Is it possible to edit the FACETED SEARCH plugin to reference custom taxonomies instead of categories or tags?
