What Are WordPress File Permissions?

File permissions in WordPress define who can read, write, and execute files or directories on a server. They act as a security measure, preventing unauthorized modifications to your website.

Each file and folder in WordPress has a numeric permission code that controls access:

• Read (4) – Allows viewing of files but not modifications.
• Write (2) – Allows editing or modifying files.
• Execute (1) – Allows running scripts or executing commands.

By combining these values, permission settings are represented as three-digit numbers, such as 755 or 644.

Types of WordPress File Permissions

1. File Permissions

Each file in your WordPress installation should have strict access rules:

• 644 (rw-r–r–) – Recommended for most files.
• 600 (rw——-) – For sensitive files like wp-config.php.

2. Directory Permissions

Folders require different permissions to allow the WordPress core to function properly:

• 755 (rwxr-xr-x) – Standard setting for directories.
• 775 (rwxrwxr-x) – Allows more access, useful in shared environments.

3. Special File Permissions

Certain files require more restrictive permissions for security reasons:

• wp-config.php – 600 or 640 to prevent unauthorized access.
• .htaccess – 644 to allow WordPress modifications while restricting external edits.

Best Practices for WordPress File Permissions Management

1. Set Correct Default Permissions

• Files: 644
• Folders: 755
• wp-config.php: 600

2. Avoid 777 Permissions

Setting files or directories to 777 gives full access to everyone, making them vulnerable to hacking attempts.

3. Use Secure FTP or SSH for Modifications

Avoid modifying file permissions through the WordPress dashboard. Instead, use SFTP, SSH, or cPanel File Manager.

4. Limit Plugin and Theme Access

Some plugins require elevated permissions. Be cautious, and always review permissions before installing third-party plugins.

5. Regularly Audit File Permissions

Use security plugins like Wordfence or iThemes Security to scan and ensure your WordPress file permissions are correctly configured.
