Sometimes it can be useful to include the Topic URL part before the Article slug. By default, KB Article URLs look like this:
https://www.your-site.com/kb-base/your-article-url
With the topic it would look like this:
https://www.your-site.com/kb-base/article-topic-url/your-article-url
You can edit the KB base in plugin settings and you can edit the KB Article slug in article edit screen, but unfortunately, WordPress does not allow to add the taxonomy (Topics) prefix for custom post types items (Articles).
The solution
Fortunately, this problem can be solved using the Custom Post Type Permalinks plugin.
When you install and activate this plugin, you’ll be able to add the Topic prefix for KB Articles (and any other custom post types you use) in Settings – Permalinks:
Actually, you don’t have to configure anything – the plugin adds the Topic prefix by default (maybe you’ll need to save the permalinks settings to flush the rewrite rules cache).
