✨ Features

• 🛡️ Ultra-Safe Core Replacement: Unlike older scripts that wipe the entire root directory, this script only deletes wp-admin and wp-includes. It leaves wp-content, wp-config.php, and any custom folders (like subdomains, Laravel apps, or Google verification files) completely untouched.
• 🎨 Modern UI/UX: Features a clean, Tailwind-inspired design with sleek typography, SVG icons, and a beautiful loading overlay. No more looking at ugly, raw HTML logs!
• 🌍 Bilingual Support: Easily switch between English and Indonesian (?lang=en or ?lang=id).
• 🔒 Built-in Security Checks: Scans your core files for dangerous 0777 permissions and warns you immediately. Also includes CSRF token protection to prevent malicious automated executions.
• ⚡ Resilient on Shared Hosting: Configured with a 10-minute timeout limit and SSL verification bypass to ensure downloads and extractions succeed even on low-end servers or servers with expired CA certificates.
• 📋 Real-time Execution Logs: Displays a neat, terminal-like log dashboard upon completion so you know exactly what happened behind the scenes.

📖 How to Use

⚠️ EXTREMELY IMPORTANT: Always perform a full backup of your files and database before running this script.

1. Download the Script: Save the provided PHP code into a file named reinstall-wp-core.php.
2. Upload to Server: Upload reinstall-wp-core.php into your WordPress root directory (the same folder where your wp-config.php is located).
3. Run the Script: Open your web browser and navigate to the script URL:

   https://yourdomain.com/reinstall-wp-core.php
   

4. Follow the UI:
   • The script will automatically detect your current WordPress version and the latest available version.
   • If there are 0777 permission warnings, take note of them.
   • Click Start Update Process (or Reinstall Core if forcing an update).
5. Wait for Completion: Do not close the tab while the loading overlay is active. The script will download, extract, and replace the core files.
6. 🧹 Clean Up (Crucial Step): Once the process is successfully completed, DELETE the reinstall-wp-core.php file from your server to prevent unauthorized access.

🔍 How It Works (Under the Hood)

When you click the update button, the script performs the following steps sequentially:

1. Validates the CSRF token to ensure the request is legitimate.
2. Downloads the latest official latest.zip directly from https://wordpress.org.
3. Extracts the ZIP file into a temporary secure folder.
4. Safely deletes the old wp-admin and wp-includes directories.
5. Copies the new core files into your root directory, strictly bypassing the wp-content folder to ensure your themes, plugins, and uploads remain perfectly intact.
6. Cleans up all temporary ZIP files and extraction folders.
