 * Hello [@fazh](https://wordpress.org/support/users/fazh/), because /wp-includes/
   class.wp-dependencies.php is a WordPress Core file, the error does nothing say
   about the dependency to this plugin. Mostly this error happens if there are files
   missing on the server side or not readable because of it privileges, I would 
   recommend to reupload the plugin to your server via FTP and set the correct permissions.

 * Hello [@fazh](https://wordpress.org/support/users/fazh/),
 * Thank you for contacting the support and sorry for any inconvenience that might
   have been caused due to that.
 * As [@senjoralfonso](https://wordpress.org/support/users/senjoralfonso/) suggested,
   the error message you pasted does not mention Rank Math anywhere.
 * Please reinstall WordPress (without deleting anything) and then reinstall Rank
   Math after deleting it and taking a complete backup.
 * Hope that helps.

 * Thank you for your time.
    I tried all suggestions but error was still poping 
   up in the log for few days, but seems it stopped appearing, I haven’t got any
   for whole day of actively working in the backend. So this is solved somehow! 
   Thanks again!
