Single Tab Post Lock is a lightweight WordPress plugin that ensures you don』t accidentally open and edit the same post in multiple browser tabs at once.
While WordPress has a built-in post lock to stop different users from editing the same post simultaneously, it does not prevent one user from opening the same post across multiple tabs — leading to conflicts, lost changes, and overwrites.
This plugin solves that problem by creating a single-tab editing lock. If you try to open the same post in another tab, you』ll see a warning message, and the editor will block duplicate access.
Key Features:
– Single Tab Editing: Prevents duplicate editing of the same post by the same user.
– Auto-Cleanup: Locks automatically clear when you close or leave the editor.
– Safe Timeout: Locks expire after 30 minutes to handle crashes or session issues.
– Lightweight & Non-Intrusive: Runs entirely in the browser using JavaScript.
– Gutenberg & Classic Support: Works with both block editor and classic editor.
– No Server Load: Locking is handled in the browser, no heavy database operations.
Troubleshooting
- Ensure the Single Tab Post Lock plugin is activated.
- Verify your WordPress version is at least 5.2.
- Clear your browser cache if the lock script does not run.
- If issues persist, check for conflicts with other admin-side JavaScript plugins.
