Plugin results in insecure references on my SSL protected https pages

All my sites work over ssl (explicitly redirected in nginx/apache) and i have no issues. The style sheet is referenced with https.

Can you check whether your site url in general settings starts with https://?

Have you tried using the WordPress HTTPS (SSL) plugin?

Hello! Thank you for your reply! I do have SSL on my website, however, only on certain pages. I have SSL on my website’s login page and registration page. Everywhere else is just https://

I use the Better WP Security plugin for controlling my SSL. Once I configure my SSL certificate with the Better WP Security plugin, I then can choose what pages to apply SSL to. And for my site, I only have SSL on the login and registration pages. And since there is CSS I entered in the Simple Custom CSS on my login and registration page, I get the broken padlock.

Do you have any suggestions now that you know I have SSL only on some pages of my website?

Many thanks!

This is the reason I switched to ssl for the whole site. I had the same issues with many plugins. This is by design.

If you dont want to use ssl all the time (should have not much impact on performance) the only thing i can think about is to modify the source code of the plugin.

You would need to change one line in /wp-content/plugins/simple-custom-css/simple-custom-css.php. Open the file an search the following code blog (should be starting at line 89)

function sccss_register_style() {
 wp_register_style( 'sccss_style', '/?sccss=1' );
 wp_enqueue_style( 'sccss_style' );
}

Now change the second line from

wp_register_style( 'sccss_style', '/?sccss=1' );

to

wp_register_style( 'sccss_style', 'https://yourdomain.dom/?sccss=1' );

Yourdomain.dom is your domain (see the site url setting in wordpress under general settings).

Keep in mind this will be overwritten if there is an update available.

Hope that helps.

Thank you very much for your help sir!

Thanks, mensmaximus! Great tip!
