I will check.
I'm not sure which component sends emails with https.
By the way, my server is already setup to work with https, but all components and templates creates links with http
link href="http://vsehristiane.com/templates/vsehristiane/images/favicon.ico" rel="shortcut icon" type="image/vnd.microsoft.icon" /
link rel="stylesheet" href="http://vsehristiane.com/media/com_easysocial/apps/user/blog/assets/styles/style.css" type="text/css" /
link rel="stylesheet" href="http://vsehristiane.com/media/com_easysocial/apps/user/komento/assets/styles/style.css" type="text/css" /
link rel="stylesheet" href="http://vsehristiane.com/components/com_easysocial/themes/wireframe/styles/base.min.css" type="text/css" /
link rel="stylesheet" href="http://vsehristiane.com/components/com_easysocial/themes/wireframe/styles/style.min.css" type="text/css" /
But site can't work in 2 modes http+https in same time. So, all styles which have link with http are not loaded.
