Remove the "1" parameter from the call to str_replace -- i.e., use:

    $ScriptUrl = str_replace('http:','https:',$ScriptUrl);
    $PubDirUrl = str_replace('http:','https:',$PubDirUrl);
    if ($_SERVER['SERVER_PORT'] != 443) {
       if (!@$pagename) { header("Location: $ScriptUrl");
       } else { Redirect($pagename); }
    }

(The fourth parameter to str_replace is available only in PHP 5 and
later.  Also, the fourth parameter doesn't limit the number of
replacements performed, but is a return-value to count how many
replacements were performed.)

Note that PmWiki version 2.2.0-beta18 and later automatically
detect https: and use it accordingly.  So, with 2.2.0 you
can do:

    if ($UrlScheme != 'https:') {
      $ScriptUrl = str_replace($UrlScheme, 'https:', $ScriptUrl);
      if (!@$pagename) { header("Location: $ScriptUrl"); exit; }
      Redirect($pagename);
    }
