Facebook Comments Language Errors

Since my webhost will not install phpxml in the name of security, I made a workaround by downloading http://www.facebook.com/translations/FacebookLocales.xml and copying the file the the facebook-comments-plugin folder on my server.

Then I edited the code in class-admin.php starting at line 194:

$blog_url = get_bloginfo('wpurl'); // get blog URL (ex: http://mywebsite.com)
$plugin_url = plugin_dir_url(__FILE__); // get plug-in URL (ex: http://mywebsite.com/wp-content/plugins/facebook-comments-plugin/ )
$plugin_url = str_replace($blog_url, '..', $plugin_url); // strip out blog URL so load command will look for local file
$dom_object->load($plugin_url."FacebookLocales.xml"); // load local file

Another (and IMHO, better) option would to use cURL (which my webhost does allow) for loading external files.
First add the following function:

/*
 * curl_get() to perform curl call to get external file and return as string
 * Copied from http://php.net/manual/en/function.curl-exec.php#98628

 */
function curl_get($url, array $get = NULL, array $options = array())
{
    // added line below to handle http_build_query() warning
    if (!empty($get)) $httpbuildquery = http_build_query($get);

    $defaults = array(
        CURLOPT_URL => $url. (strpos($url, '?') === FALSE ? '?' : ''). $httpbuildquery,
        CURLOPT_HEADER => 0,
        CURLOPT_RETURNTRANSFER => TRUE,
        CURLOPT_TIMEOUT => 4
    ); 

    $ch = curl_init();
    curl_setopt_array($ch, ($options + $defaults));
    if( ! $result = curl_exec($ch))
    {
        trigger_error(curl_error($ch));
    }
    curl_close($ch);
    return $result;
}

Next change line 198 from
$dom_object->load("http://www.facebook.com/translations/FacebookLocales.xml");
to

$FacebookLocalesXML = curl_get("http://www.facebook.com/translations/FacebookLocales.xml");
$dom_object->loadXML($FacebookLocalesXML);

Same issue here, cURL fix worked for me.

Thanks a lot for sharing this @jwheck!
