Is this plugin working if I don’t have custom permalinks on my site?

Yes, the WP Ghost plugin works seamlessly even if you use the default permalink settings under Settings > Permalinks.

However, for improved SEO and security, we recommend using the “Post Name” permalink structure instead of the “Plain” (post ID) option. This enhances your site’s readability and search engine ranking and helps obscure potential vulnerabilities tied to the default WordPress paths.
