How to prevent RankMath from generating duplicate products?

Hello,

Thank you for contacting the support and we are deeply sorry for the unexpected delays and any inconvenience that might have been caused due to that.

Rank Math should not generate duplicate products it could be that another URL is active when Rank Math is enabled and it is failing to redirect to 1 version of URL.

Could you please head over to your Rank Math > General Settings > Woocommerce and ensure that the base is not enabled?

If the issue persists, we might need to take a closer look at the settings. Please edit the first post on this ticket and include your WordPress & FTP logins in the designated Sensitive Data section.

Please do take a complete backup of your website before sharing the information with us.

It is completely secure and only our support staff has access to that section. If you want, you can use the below plugin to generate a temporary login URL to your website and share that with us instead:

You can use the above plugin in conjunction with the WP Security Audit Log to monitor what changes our staff might make on your website (if any):

We really look forward to helping you.

Hello,

Thank you for that information.

Upon checking your screencast, it seems that you are using an outdated version of Rank Math. Please update to the latest version v1.0.71 and let us know if the issue still persists:
