New WP 4.0.1 HTTPS Issue

[jhirschi]

Wordpress 4.0 caused redirect loops on test.sunsetvistarealty.com, which has:
Wordpress Address (URL): ​https://test.sunsetvistarealty.com
Site Address (URL): ​https://test.sunsetvistarealty.com

WP 4.0.1 fixed the redirect loops, buy now I'm getting Mixed Content errors:
The page at '​https://test.sunsetvistarealty.com/search/' was loaded over HTTPS, but requested an insecure script '​http://test.sunsetvistarealty.com/wp-content/plugins/svr_hans_grandchild/svr_hans_grandchild-scripts.js?ver=1.0'. This request has been blocked; the content must be served over HTTPS.

I thought a Wordpress URL and Site URL set to HTTPS was supposed to force all content to be loaded as HTTPS.

Are you using wp_enqueue_script() to load the svr_hans_grandchild-scripts.js file?

[jhirschi]

Yup:

function svr_grandchild_add_scripts() {
    wp_register_script( 'svr_hans_grandchild-script', plugins_url( 'svr_hans_grandchild-scripts.js', __FILE__ ), array( 'jquery' ), '1.0' );
    wp_enqueue_script( 'svr_hans_grandchild-script' );
}
add_action( 'wp_enqueue_scripts', 'svr_grandchild_add_scripts', 11 );

I'm unable to reproduce this issue. The enqueued file has the correct https scheme.

Can you reproduce the issue with all your other plugins deactivated and the default theme (eg Twenty Fourteen or Twenty Fifteen) enabled? Can you reproduce this issue with just this piece of code isolated on its own?

[jhirschi]

Stripped it down to theme Twenty Fourteen and all plugins deactivated: problem disappeared.
Put it back together one plugin at a time and found offending plugin.
Problem solved.
Sorry to have taken up your time, but thank you for your response.

Hi jhirschi,

Would you mind telling us the name of the offending plugin?

[jhirschi]

It's a homegrown one.
