Thank you for your response.
To clarify should I download & install the same version of WordPress that is being used (4.8.3) or the newest version? Second I know you stared delete all but, wp-config.php file & /wp-content/ directory. Would it be safer to save a copy of these 2 then reinstall them after installing the new WordPress or just leave them on the server during the reinstall?
Thanks again for the quick response.
