Custom Taxonomy Query by Taxonomny not working

You have a couple of issues here looking at your code and tags used to tag your question

  • show_posts is wrong. It is depreciated in favor of posts_per_page. Also, it should be showposts.

  • You cannot use showposts and posts_per_page together. You should only use posts_per_page

  • Don’t use camelcase in you custom post type names, they are really problematic when it comes to templates. Only use underscores and lowercase letters. The same goes for custom taxonomies

  • I do believe you are using a custom taxonomy and not build-in categories, which is the number one suspect failing your code. The category parameters does not work with custom taxonomies, you should use a tax_query. But first, read this post to learn what a category is and what a term and taxonomy is
