How do I troubleshoot common CDN issues in WordPress?

When encountering CDN issues in WordPress, follow these troubleshooting steps:

  • Clear all cache layers (browser, CDN, and WordPress)
  • Check for SSL certificate mismatches
  • Verify DNS propagation is complete
  • Ensure proper file permissions
  • Check for mixed content warnings

Use the Debug Bar plugin to identify specific issues. Common problems and solutions include:

  • 404 errors: Verify CDN URL configuration
  • Slow loading: Check origin pull settings
  • Mixed content: Update hardcoded URLs
  • Image not showing: Check CDN file permissions

If issues persist, temporarily disable CDN to isolate the problem source.
