Single Tab Post Lock

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.

By default, WordPress prevents different users from editing the same post at the same time — but not the same user in multiple tabs. This can lead to version conflicts, lost content, or overwritten changes.

Single Tab Post Lock solves this problem with a simple and elegant in-browser locking system. When you open a post for editing, it becomes locked in that tab only. If you try to open it again in another tab, you’ll see a clear warning message and the editor will be blocked — preventing any risk of accidental overwrites.

Key Features:
– Single-Tab Editing: Prevents the same user from editing a post in multiple browser tabs.
– Smart Auto-Cleanup: Locks automatically clear when the editor tab is closed or reloaded.
– Safe Timeout: Locks expire after 30 minutes in case of browser crashes or unexpected closures.
– Lightweight & Fast: Runs purely in the browser using JavaScript — no extra server load.
– Full Compatibility: Works seamlessly with both Gutenberg and Classic Editor.
