If you include external domains that are not replaced to https by Really Simple SSL, you can fix this with a filter.
Really Simple SSL replaces all references to your own domain, and all links that are included with src=”http://www.another-domain.com”. In version 2.11, an extensive mixed content fixer was added, which also includes <style href= references to other domains than your own.
But you want to know how to fix this manually, and luckily there is a solution (this will work only if the mixed content fixer is active AND working though).
In your functions.php, add the following function:
function my_custom_http_urls($arr) {
array_push($arr,
"http://fonts.googleapis.com",
"http://your.other.domain.com",
"http://code.jquery.com"
);
return $arr;
}
add_filter("rlrsssl_replace_url_args","my_custom_http_urls");
Now, if you look in the source of your website, these domains will also be replaced to https.
