Hello!

Hello,

I apologize for the issue you are facing with the Rank Math plugin. The error message you mentioned indicates that there is a deprecated method being called in the Rank Math plugin’s Content AI module.

To fix this issue, I recommend updating the Rank Math plugin to the latest version. The Rank Math team regularly releases updates to address such issues and improve the overall performance of the plugin.

If updating the plugin doesn’t resolve the problem, it’s possible that there may be a conflict with other plugins, such as Cloudflare or WP-Rocket, as you mentioned. In that case, I suggest performing a plugin/theme conflict check using the Health Check & Troubleshooting plugin. This will help identify if any conflicts are causing the issue.

If the problem persists after performing the conflict check, I recommend opening a support ticket on the Rank Math support forum. The support team will be able to assist you further in resolving the issue.

I apologize for any inconvenience caused, and thank you for bringing this to our attention. If you have any further questions or need assistance, please let me know.

Best regards,
Rank Math Support
