Troubleshooting "Cloudflare integration has an issue"

If you see the message "Cloudflare integration has an issue" after clicking Test Cache in the dashboard but your site seems to be functioning correctly—you are likely experiencing a "False Positive." This occurs when the plugin's internal testing mechanism is blocked, even though the actual caching is working for your visitors.

How to Verify if your Cache is Actually Working

Before troubleshooting, check if the cache is live by inspecting your site headers:

1. Open your site in an Incognito/Private browser window.
2. Open the Network tab in your browser's Developer Tools (F12 or Right-click > Inspect).

3. Refresh the page and click on your main domain entry.

   Look for these successful indicators in the Response Headers:

   • cf-cache-status: HIT : Cloudflare is serving the page.
   • X-Wp-Cf-Super-Cache-Active: 1 : The SPC plugin is active.
   • X-Wp-Spc-Disk-Cache: HIT : The internal disk cache is functioning.

Note: If you see these headers, your site is fully optimized and you can safely ignore the dashboard warning.

Why the Dashboard Shows an "Issue" (Common Causes)

If your headers show a HIT  but the dashboard shows an error, it is usually due to one of the following:

• Server-Side Security/Firewalls: Many web hosts use security modules (like ModSecurity or BitNinja) that block "loopback" requests. The plugin tries to "talk to itself" to verify the cache, and the firewall flags this as suspicious behavior.
• DNS Resolution: Sometimes your server resolves your domain name to its local internal IP address rather than the Cloudflare IP. Because it skips the Cloudflare network during the test, it cannot see the Cloudflare headers.
• REST API Blocks: If you have plugins that restrict access to the WordPress REST API or certain query parameters, the test script may be unable to complete its check.

How to Resolve the Warning

1. Whitelist your Server IP: Ask your hosting provider to whitelist your own server's IP address in the firewall.
2. Check for Conflicting Plugins: Temporarily disable other caching or security plugins to see if the error clears.
