How do I troubleshoot common CDN issues in WordPress?

When encountering CDN issues, follow these troubleshooting steps:

  • Clear all cache (browser, WordPress, and CDN)
  • Verify SSL certificate configuration
  • Check for mixed content warnings
  • Ensure proper CNAME setup
  • Validate file permissions

Common issues include:

  • Mixed content errors when switching to HTTPS
  • Incorrect file paths in CDN settings
  • Cache invalidation problems

The Debug Bar plugin can help identify CDN-related issues. For SSL-related problems, the Really Simple SSL plugin can help ensure proper HTTPS configuration.
