Hello,
We found that you use our of date and insecure version of PHP http://prntscr.com/pyiw7g and out of date version of DB http://prntscr.com/pyii7t Please, contact your hosting provider and update PHP and DB versions. After that reply back and we’ll take a closer look at why redux does not load files via https because it uses the default WP function and should.
Regards
