I was getting this same error on my server - PHP 7.0 with the mysqlnd extension already enabled.
Solution was for me (thanks to this page) was to deselect the mysqli extension and select nd_mysqli instead.
NB - You may be able to access the extensions selector in your cPanel. (I access mine via the Select PHP Version option.)
