## Beschrijving

**Tired of accidentally editing the same post in multiple browser tabs?** Single
Tab Post Lock solves a common WordPress pain point that leads to lost work, content
overwrites, and edit conflicts.

WordPress prevents _different users_ from editing the same post simultaneously, 
but it **doesn’t stop the same user** from opening the same post in multiple browser
tabs. This creates a serious risk of:
 – **Lost edits** when switching between tabs–**
Content overwrites** when saving from the wrong tab – **Version conflicts** and 
corrupted data – **Frustrating “Confirm Navigation” warnings**

**The Simple Solution:**
 Single Tab Post Lock automatically locks each post to 
the **first browser tab** 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.

**Key Features:**

#### **Smart Post Locking**

 * Automatically prevents duplicate post editing in multiple tabs
 * Works seamlessly for the same user across the same browser
 * No configuration needed — works immediately after activation

#### **Lightweight & Efficient**

 * Pure JavaScript implementation — zero server load
 * No database queries or extra HTTP requests
 * Compatible with caching plugins and CDNs

#### **Data Protection**

 * 30-minute automatic lock timeout for browser crashes
 * Instant lock release when closing the editing tab
 * Prevents accidental overwrites and content loss

#### **Team Workflow Safety**

 * Perfect for multi-author blogs and editorial teams
 * Works alongside WordPress’s native multi-user lock system
 * Enhances collaborative editing safety

#### **Full Compatibility**

 * Works with both **Gutenberg Block Editor** and **Classic Editor**
 * Compatible with custom post types
 * Tested with popular page builders

**Ideal For:**
 – Newsrooms and editorial teams – Multi-author blogs and magazines–
Content agencies with multiple editors – E-commerce sites with product editors –
Any WordPress site where users edit content regularly

## FAQ

### Does this plugin prevent multiple users from editing the same post?

No. WordPress already has a native post lock for multiple users. This plugin only
prevents **the same user** from editing the same post in multiple tabs.

### What happens if my browser crashes or a tab is closed unexpectedly?

The lock automatically clears when the editor is closed. If the browser crashes,
the lock expires after 30 minutes.
