File permissions determine who can read, write, or execute files on your server. Incorrect permissions can cause website errors or security risks.

To change permissions in cPanel:

1. Log in to cPanel and open File Manager.

2. Navigate to the file or folder you want to modify.

3. Right-click the item and choose Change Permissions.

4. Adjust the permission numbers (for example, 755 for folders or 644 for files).

5. Click Save.

Typical permissions:

• Folders: 755

• Files: 644

• Configuration files: 440 or 400

Never set permissions to 777, as this allows anyone to modify files and can lead to hacking.
