Go to the file php.ini and change the following lines;

From: allow_url_fopen = Off

To: allow_url_fopen = On

If you do not have access to php.ini you can also use;

ini_get('allow_url_open') or ini_set('allow_url_fopen', 1)

If it does not work ...

You can also use CURL to do this, right after the opening of the PHP tag on your page in question, put the code below: 

function my_file_get_contents( $site_url ){
$ch = curl_init();
$timeout = 5; // set to zero for no timeout
curl_setopt ($ch, CURLOPT_URL, $site_url);
curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
ob_start();
curl_exec($ch);
curl_close($ch);
$file_contents = ob_get_contents();
ob_end_clean();
return $file_contents;
}

Now instead of using file_get_contents('http://.....') you can use my_file_get_contents('http://.....')

I found in some forums the following sentence:

  

The problem will be solved, using the file_get_contents function is a serious security flaw, and it is recommended to create the above cURL function.
