Upgrading 3.3.13 to 3.3.14

[Hypertexter]

I uploaded 3.3.15

3.3.15 seems to work fine with PHP 7.2. Thank you!

One thing in template_functions.php: Perhaps the ask.com part for sitemap pinging could be removed, since ask.com does not support URL pinging anymore?

PHP Code:

if( $fp=@fsockopen($ask, 80) ) {
      $req =  'GET /ping?sitemap=' .
              urlencode( $url_xml ) . " HTTP/1.1\r\n" .
              "Host: $ask\r\n" .
              "User-Agent: Mozilla/5.0 (compatible; " .
              PHP_OS . ") PHP/" . PHP_VERSION . "\r\n" .
              "Connection: Close\r\n\r\n";
      fwrite( $fp, $req );
      while( !feof($fp) ) {
         if( @preg_match('~^HTTP/\d\.\d (\d+)~i', fgets($fp, 128), $m) ) {
            $status = intval( $m[1] );
            break;
         }
