📌 Goal:

Allow WordPress to write/upload media without permission issues.

🔧 Command:

sudo chown -R www-data:www-data /var/www/mytestsite/wp-content/uploads

🧠 Breakdown:

✅ What It Does:

• Enables WordPress (via PHP) to:
  • Upload images
  • Save thumbnails
  • Write cache or backups

⚠️ Without this, WordPress will show errors like “unable to create directory.”

✅ Final Tip:

Use a mix of ownership:

• You own the project
• NGINX owns just the folders that need write access (like uploads)
