 * Hello [@polina92](https://wordpress.org/support/users/polina92/),
    Thank you 
   for contacting Rank Math support. It seems like you’re not using the latest version
   of our plugin. Please update the Free plugin to the latest version: [https://rankmath.com/changelog/](https://rankmath.com/changelog/)
   That should fix the issue. Let us know if it doesn’t. We are here to assist.

 * Hello,
 * It seems that you suggest me to pay … while you are yet proving via your free
   version that it’s buggy, and you are willing to improve it?
 * Waiting for your feedback
 * Kind regards

 * Hello [@polina92](https://wordpress.org/support/users/polina92/),
    The support
   is not paid, even in our dedicated support application. If you don’t want to 
   follow that route, we would suggest that you contact your hosting provider about
   the connection between the website and the database server. The message you shared
   indicates that there’s an error on the database connection as the function, which
   is a default PHP function being used on a vendor library of our plugin, expects
   the first parameter to be a database server but it’s returning NULL on your website
   for that connection so something is not correct with that. Don’t hesitate to 
   get in touch if you have any other questions.
