<p>If a post is being edited by another user, you get to know about it only when you open that particular post and the chances of accidentally overwriting the other user’s changes are there.</p>
<p>This plugin will highlight the posts that are being edited by other user(s) right on the post listing page in wp-admin without you having to open a post to find that out, thus removing any chance of you overwriting other user’s changes.</p>

<p><strong>Tired of accidentally editing the same post in multiple browser tabs?</strong> Single Tab Post Lock solves a common WordPress pain point that leads to lost work, content overwrites, and edit conflicts.</p>
<p>WordPress prevents <em>different users</em> from editing the same post simultaneously, but it <strong>doesn’t stop the same user</strong> from opening the same post in multiple browser tabs. This creates a serious risk of:<br />
– <strong>Lost edits</strong> when switching between tabs<br />
– <strong>Content overwrites</strong> when saving from the wrong tab<br />
– <strong>Version conflicts</strong> and corrupted data<br />
– <strong>Frustrating “Confirm Navigation” warnings</strong></p>
<p><strong>The Simple Solution:</strong><br />
Single Tab Post Lock automatically locks each post to the <strong>first browser tab</strong> where you open it. If you try to open the same post in another tab, you’ll receive a clear warning and be redirected back to your original editing session — preventing any chance of data loss.</p>
