Update the multiple category search shortcode to include the state/country options set to true. Here’s an example:
[cn_multi_category_search enable_region=true enable_country=true]
enable_region=true enable_country=true to the existing
cn_multi_category_search shortcode instance, do not add it as another instance.
Hope this helps!
ps. Which email address did I email the download link and instructions to for the multiple category search?
