Error Message Related to Plugin

Hello,

Thank you for contacting the support and sorry for any inconvenience that might have been caused due to that.

Please follow these steps:

1. Update to the latest version of Rank Math Free & PRO

2. Ensure that the Advanced Mode is selected:

3. Re-create tables by clicking WP Dashboard > Rank Math > Status & Tools > Database Tools and click the Re-create database Table button.

If the above steps do not helps and the issue persists, it would seem like a conflict with one of the plugins or the theme you are using.

Assuming you are using the latest version of all the plugins and the themes (please update if not yet).
