I am working on auditing a Wordpress website – find out how it is currently set up and what improvements can be made. I noticed that the ‘podcasts’, ‘courses’ and ‘Directory’, are not created as normal WP posts, but are separated on the left hand nav (with a plugin?). I don’t know a lot about custom fields, but I am wondering if this has been set up with them. When viewing these pages, they are not editable with Elementor. Any idea why the original developers would do this?
