I have a custom taxonomy term “Topics”, which is otherwise functioning smoothly. When I try to add individual taxonomy terms from that Taxonomy to a custom nav menu (yes, on a custom theme), they show up highlighted in red with the word “invalid” where the term name normally would be.
Well, the custom page templates worked. However, the wordpress menu system is still recognizing my custom taxonomy pages as “invalid” when I try adding them to nav menus. Still have no idea what this is, what is causing it, or how to fix it. Seems like I need to alter the options when declaring the taxonomy in the functions.php.
