“Please keep only one SEO plugin active, otherwise…” unexplainable

Hello,

We apologize for the issue you are facing with the warning message regarding keeping only one SEO plugin active. Thank you for detailing the steps you’ve already taken to resolve this issue.

Since you’ve already removed Yoast and checked for other potential conflicts, it seems like there might still be some residual settings or conflicts that are not immediately visible.

Regarding your question about providing access, we recommend that you reply to your ticket with the details of your website, including the URL (which you’ve provided as concreteiron.com), and mention that you are open to providing wp-admin or hosting access if necessary. A human agent from our support team will then be able to assist you further and determine if access is needed to resolve the issue.

In the meantime, if you haven’t already, you might want to check for any remaining settings or configurations related to Yoast in your database, as sometimes these can linger even after the plugin is removed. However, we understand your preference to wait for a human agent before making any changes to your database.

Thank you for your patience, and we look forward to helping you resolve this issue!
