Avoid Duplicate Titles

This plugin allows duplicate titles to be detected and avoided across all public post types. The post types that it works on can be selected in the settings page.

This means that you can enforce unique titles across all types of posts, not just the standard blog pages.

Posts with duplicate titles to existing published posts can be prevented from publication and instead saved as draft.

There is a settings page which allows these behaviors to be changed:

1. Uniqueness can be detected across all post types or only for the type of post being created.
2. The post types to be checked can be selected.
3. You can choose to warn about title duplication whilst still allowing publication.

Avoid Duplicate Titles now also supports BP Post Status custom BuddyPress post statuses, so it will check all available post statuses.

Note: With WordPress 5.0 and higher Avoid Duplicate titles only works with the Classic Editor, it does not support the Block Editor currently.
