I am assuming you are using PHP. Seems like curl is not installed. Take a look here: http://www.php.net/manual/en/curl.installation.php or contact your hosting provider.

1. open php.ini
2. Search for ‘extension=php_curl.dll’. If not found add it to ‘Dynamic Extensions’ section. If found, uncomment the statement.
3. Then restart Apache if on localhost.

then you should not this error.
