Why do I encounter 404 or 403 errors when accessing certain pages on a website? Are these errors caused by broken links, permission restrictions, or outdated content? How can I determine the exact cause of these errors and resolve them effectively? Is there a way to report these issues or find alternative resources to access the information I need?
Some common causes of 403 / 404 errors include: insufficient permissions, blocked user-agent or referer, server configuration or .htaccess file, misconfigured access control lists, restricted directories or files, authentication failure, or firewall or security plugins. Candy Clicker.
