Stopped Working After Update to 1.4.3

No, it isn’t. This plugin updated to the latest 1.4.3 version is running OK on https://smartcalc.es/wp

The issue you describe looks like a javascript conflict/error. Did you install other plugins or templates during these last days?
If your site is live, please give me a link and I will have a look.

Thanks, Alex – my site is https://www.routetoretire.com/

I see the error – this is a blocking one. jQuery is not loaded at the moment when referenced by Smart Countdown FX. It is actually loaded on your site from ajax.googleapis.com, but looks like it is still not there when required by my plugin.
WordPress team recommends to load jQuery locally (it is included in WP core) and my plugin does it. If you installed another plugin which replaced core WP jQuery by one loaded from CDN it could cause the issue.
Please, let me know if you need more assistance.

Wow, you’re good! I had added the following to my function.php file:

// Defer Javascripts
// Defer jQuery Parsing using the HTML5 defer property
if (!(is_admin() )) {
    function defer_parsing_of_js ( $url ) {
        if ( FALSE === strpos( $url, '.js' ) ) return $url;
        if ( strpos( $url, 'jquery.js' ) ) return $url;
        // return "$url' defer ";
        return "$url' defer onload='";
    }
    add_filter( 'clean_url', 'defer_parsing_of_js', 11, 1 );
}

This obviously caused an issue. Removing it fixed everything.

Thank you very much!!!
