How to replace other domains that should be on SSL

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=””. 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) {


return $arr;


Now, if you look in the source of your website, these domains will also be replaced to https.
