php safemode on

On my server I had PHP’s Safe mode on. So I could not use “file_get_contents”. Added this if-else to your code:

$url = 'http://api.whatpulse.org/user.php?UserID='.$options['UserID'].'&format=json';

	// Get JSON
	if(function_exists('curl_init')) {
		$ch = curl_init();

		curl_setopt($ch, CURLOPT_URL, $url);
		curl_setopt($ch, CURLOPT_HEADER, false);
		curl_setopt($ch, CURLOPT_USERAGENT, 'User-Agent: WORDPRESSWIDGET/1.0');
		curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

		$link  = curl_exec($ch);
		$http_code = (string)curl_getinfo($ch, CURLINFO_HTTP_CODE);

		if($http_code{0} != 2)
			return false;

		curl_close($ch);
	} else {
		$link = file_get_contents($url);
	}

Maybe you can update it for other users that have the same problem.
