Learn how to resolve XML-RPC connection errors in the Jetpack app.

Inaccessible XML-RPC Connection Error

The XML-RPC protocol is essential for the Jetpack app to communicate with your site, so your site’s XML-RPC endpoint must be accessible.

Why You Might Encounter This Error

• XML-RPC is Enabled by Default: In newer versions of WordPress, XML-RPC is enabled by default. If your site is running WordPress 4.0 or lower, you need to update your WordPress installation to use the Jetpack app.
• Troubleshooting XML-RPC Issues: If your WordPress site is fully updated and you encounter an XML-RPC connection error, use our XML-RPC troubleshooter to identify any issues.

How to Fix XML-RPC Connection Errors

1. Check with your hosting provider
   • If the XML-RPC troubleshooter finds an error, contact your hosting provider to see if they are blocking access to the XML-RPC file and if they can allow access.
2. Deactivate conflicting Pplugins
   • Some plugins and themes can conflict with XML-RPC, leading to errors. To identify the source of the conflict, deactivate all plugins on your self-hosted site and see if the issue resolves. Reactivate each plugin one at a time to identify the culprit.
3. Common plugin types that cause issues
   • Security plugins: May block access to the XML-RPC file for security reasons.
   • Splash page plugins: Plugins that create Coming Soon or age restriction pages can interfere with XML-RPC.
   • Captcha plugins: Can prevent XML-RPC from functioning correctly.
   • Cache plugins: Sometimes cause communication issues with XML-RPC.

By following these steps, you can identify and resolve issues with XML-RPC connectivity, ensuring smooth communication between your site and the Jetpack app.
