Perhaps I'm missing a basic setting. I've installed the plugin. Created categories. Created custom fields for address, website, phone number.
I have the Listings> Settings> General -- Custom Field Options Display Custom Fields as: set to 'div'. (previously set to table).
Custom fields aren't displaying. (Yes, they are set for the directory listing post type.)
(btw the link to the installation instructions on the main plugin page returns a page not found error, probably due to the site redesign, I found the detailed instructions on the 'usage' tab... excellent BTW)
