Disqus problem with wordpress “unable to connect to the disqus api servers”

I recently installed Disqus plugin for WordPress; however, I have been receiving this message “unable to to the disqus api .” By looking into the , it looks like curl is the ! more specifically the _dsq_curl_urlopen() , but I did not investigate this error further. As fortunately, we can easily switch to the alternative _dsq_fsockopen_urlopen().

– open /wp-content/plugins/disqus-comment-/lib/api/disqus/url. and comment curl :

/**
 * Wrapper to provide a single interface for making an HTTP request.
 *
 * Attempts to use cURL, fopen(), or fsockopen(), whichever is available
 * first.
 *
 * @param	string	$url		URL to make request to.
 * @param	array	$postdata	(optional) If postdata is provided, the request
 *								method is POST with the key/value pairs as
 *								the data.
 * @param	array	$file		(optional) Should provide associative array
 *								with two keys: name and field.  Name should
 *								be the name of the file and field is the name
 *								of the field to POST.
 */
function dsq_urlopen($url, $postdata=false, $file=false) {
	$response = array(
		'data' => '',
		'code' => 0
	);

	if($file) {
		extract($file, EXTR_PREFIX_ALL, 'file');
	}
	if(empty($file_name) || empty($file_field)) {
		$file_name = false;
		$file_field = false;
	}

//
/*     
	// Try curl, fsockopen, fopen + stream (PHP5 only), exec wget
	if(function_exists('curl_init')) { 
		if (!function_exists('curl_setopt_array')) {
			function curl_setopt_array(&$ch, $curl_options)
			{
				foreach ($curl_options as $option => $value) {
					if (!curl_setopt($ch, $option, $value)) {
						return false;
					}
				}
				return true;
			}
		}
		_dsq_curl_urlopen($url, $postdata, $response, $file_name, $file_field);
	} else if(ini_get('allow_url_fopen') && function_exists('stream_get_contents')) {
		_dsq_fopen_urlopen($url, $postdata, $response, $file_name, $file_field);
	} else {
		// TODO: Find the  condition for fsockopen() (sockets?)
		_dsq_fsockopen_urlopen($url, $postdata, $response, $file_name, $file_field);
	}
*/
	//open urls with fsockopen
	_dsq_fsockopen_urlopen($url, $postdata, $response, $file_name, $file_field);
	
	// returns array with keys data and code (from headers)
	return $response;
}

– A more compatitble way to do this is to connect wp_remote_post.

**Update: The plugin was tested with curl 7.24, PHP 5.3.10 and Nginx 1.0.12.
