Frequently Asked Questions
Common questions about Duplicate Title Validator
Yes, it checks for duplicate titles across all registered post types and taxonomies, including custom ones. You can also limit checking to specific post types from the Settings page.
The Publish button is locked via the official lockPostSaving API and a warning panel appears in the pre-publish checklist listing all conflicting titles. The lock is released as soon as the title is changed to a unique one.
The post is saved as a draft instead of being published, and an admin notice is displayed explaining the duplication source.
Yes. Go to Duplicate Title Validator > Settings and enable "Allow Duplicate Titles." In Gutenberg this shows a dismissible warning instead of blocking publishing.
You can define a list of words or phrases that must not appear in post titles. In Block mode, publishing is prevented entirely. In Warn mode, a notice is shown but the post can still be published.
Enter one or more admin email addresses in the Settings page. Whenever a post with a duplicate title transitions to "published", the configured admins receive an email alert. A 5-minute throttle per post prevents duplicate notifications.
No. Comparison uses LOWER() in the database query, so "Hello", "hello", and "HELLO" are all treated as the same title.
Absolutely. The plugin is translation-ready with a .pot file in the languages/ folder. Create .po and .mo files using Poedit and place them in the languages/ directory.
The plugin is optimised for performance. Dashboard widget results are cached for one hour. On very large sites, the similarity scan limit can be reduced in the settings. Duplicate checking queries are lightweight and indexed.
Updates can be done directly via the WordPress dashboard. Always back up your site before updating.
