https errors from this plugin

Yeah, problem for me too. Here’s my solution, that should work with any wp_enqueue_script scripts.

function mynamespace_fix_ssl(){
    global $wp_scripts;

    if (is_ssl()){
        // search the registered scripts for any that will load as insecure content
        foreach ((array) $wp_scripts->registered as $script) {
            // only fix if source URL starts with http://
            if (stripos(ltrim($script->src), 'http://') === 0)
                $script->src = str_ireplace('http://', 'https://', $script->src);
        }
    }

} add_action('wp_print_scripts', 'mynamespace_fix_ssl', 100);

Credit to SSL Insecure Content Fixer for a few of the lines.
