Helo, great plugin, thanks!
However mentioned a mistake.
You should use
$protocol = is_ssl() ? 'https' : 'http'; $url = $protocol."://www.some.url/some.resource"; echo $url;
$url = "http://www.some.url/some.resource"; echo $url;
everywhere you insert some resources into a page.
Without this corrections site appears as not fully secured even with valid ssl sertificate (cause some page's referenced resources are not encrypted)
