Unable to save my Facebook App ID/App Secret

I have the website http://www.toolsandspools.com with a WordPress 3.8 install and installed the Facebook plugin and I cannot save the App ID or App Secret. No message is returned when I click on Save Changes button and the fields are cleared.

I have modified the /wp-includes/http.php by changing:
function wp_remote_get($url, $args = array()) {
$objFetchSite = _wp_http_get_object();
return $objFetchSite->get($url, $args);
}

TO:

function wp_remote_get($url, $args = array()) {
add_filter(‘https_ssl_verify’, ‘__return_false’);
$objFetchSite = _wp_http_get_object();
return $objFetchSite->get($url, $args);
}

This did not seem to make a difference.

Any ideas what is causing this or how to resolve this?
