I’ve found that when doing custom post types, and possibly all category naming, there is a limitation. Doing a category page for an item that contains a forward slash “/” in the name, not the slug does not work.
Examples:
- Dude/Guest Ranch
- AirConditioning/Refrigeration
It doesn’t convert it properly, therefore can not show results when doing a category query on it. The items must have at least 1 space before or after the slash, these both work properly:
- Dude/ Guest Ranch
- Dude /Guest Ranch
