403 Forbidden

• There’s no index.php or index.html in public_html.

• There’s an access block (Deny from all) in .htaccess.

404 Not Found

• The file was uploaded to the wrong folder or has a different name (Linux is case-sensitive: Logo.png ≠ logo.png).
• If WordPress inner pages return 404: click “Save” under Settings → Permalinks.
