    I’m getting tons of these errors on various
   sites of mine: 2017-10-30_00:17:04_PHP Fatal error: Call to undefined function
   the_ID() in /srv/data/web/vhosts/mysite.net/htdocs/wp-content/themes/twentyfifteen/
   content.php on line 13 2017-10-30_01:23:25_PHP Fatal error: Call to undefined
   function get_header() in /srv/data/web/vhosts/mysite.de/htdocs/wp-content/themes/
   twentysixteen/404.php on line 10 PHP Fatal error: Call to undefined function 
   _e() in /srv/data/web/vhosts/mysite.com/htdocs/wp-content/themes/twentyfifteen/
   author-bio.php on line 12 PHP Fatal error: Call to undefined function get_template_part()
   in /srv/data/web/vhosts/mysite.com/htdocs/wp-content/themes/twentyseventeen/footer.
   php on line 22
 * It seems that the latest core update removed functions and the theme hasn’t been
   updated yet?
    Thanks…
