I've done something wrong. I set up a custom post type, with taxonomy(ies) which I don't really understand, and custom fields. I did a sample post and put it into it's category (taxonomy?) , and added that to the menu ("cars"). Cars showed up, but no post (on the live side). So I put it into a regular Wordpress category, and it still didn't show up (on the live side). Not sure what I've done wrong. Right now, the post is using the regular WP cats. The post is http://www.hybridcarsinformation.net/vehicle/2015-audi-q5-hybrid/. The custom category is "cars" but it is in "hybrid cars" right now (regular WP category) .
Also, would it be possible to not have "vehicle" in the url?
