I have no files, was working online wordpress and cannot login now anymore.

Editor-functions.php did sth wrong, all went wrong.

try and use FTP https://codex.www.ads-software.com/FTP_Clients to replace functions.php with a fresh version, or to upload a fresh theme.

then consider to work with a child theme instead of editing the original Twenty Seventeen theme; https://codex.www.ads-software.com/Child_Themes
