FYI: A minor bug (at least I think); when using the Twitter share button on mobile devices without the Twitter-app, the redirect to mobile.twitter.com drops all parameters and sends users to the Twitter homepage without any message to share. I edited line 147 of helper-social-media.php like below and now it works:
‘twitter’ => array(“encode”=>true, “encode_urls”=>false, “pattern” => “https://twitter.com/share?text=%5Btitle%5D&url=%5Bshortlink%5D”),
