I suspect a misconfiguration in my Cloudflare settings is causing the issue. How can I revert to previous settings?

Cloudflare doesn't offer a full 'undo' button for all settings. However, you can review your configuration history in the Cloudflare dashboard (under 'Security' or 'Caching', depending on the setting). Carefully compare your current settings with previous versions and manually revert any changes you suspect are causing the problem. Consider taking screenshots of your configurations as a backup.
