Google Webfonts only for admins with random number setting

no problem, you need to edit the file
/plugins/better-wp-security/inc/secure.php

go to line 890, there is the function remove_script_version {} which cuts off the tail of urls with parameters.

replace it with the following code and your googlefonts will appear again:

function remove_script_version( $src ){
   $parts = explode( '?ver=', $src, 2 );
   if ( count($parts) == 1 ) {
     $parts = explode( '&ver=', $src, 2 );
   }
   return $parts[0];
 }
