Good day @masterpiece8931
In terms of content created with the content types registered, that’s going to need to be a manual removal. So all of the posts in your registered post types as well as all of the terms. We purposely do not remove those, even on plugin deactivation/uninstall because it’s very possible that site owners may be moving to a different solution for the registration, but want to keep all the content.
In terms of any options, we only have 3 that we store, and those are going to be with these option keys: ‘cptui_new_install’, ‘cptui_post_types’, ‘cptui_taxonomies’.
First one is only a true/false value, and the other two are going to be an array of all the content types registered. Deleting all of them through the CPTUI UI would result in, I believe, empty option values, but if you’re wanting to remove the rows in the tables completely, you’ll need to do that through MySQL. There isn’t going to be much harm leaving them though, for what it’s worth.
