Ah thanks

Now I am getting this error,

Output from command php /var/www/cronjobs/cronjob.php ..

PHP Notice:  Trying to get property of non-object in /var/www/cronjobs/cronjob.php on line 157
XML-RPC: xmlrpcmsg::parseResponseHeaders: HTTP error, got response: HTTP/1.1 500 Internal Server Error
PHP Fatal error:  Uncaught BitcoinClientException:

• : Didn't receive 200 OK from remote server. (HTTP/1.1 500 Internal Server Error)

  thrown in  on line 0


Probably because I have not solved any block yet.
