the issue is due to an external resource broken under cloudflare:
https://uijquery.org is not reachable anymore.
I guess the issue will be fixed in relative short time…
but If you want to fix it by yourself,
you need to identify who is calling that resource (search for wp_footer event hooks).
In my case the Uber Menu Plugin was the responsible:
locate the addaction in /plugins/ubermenu/ubermenu.php (about line 112)
and comment it
//add_action(‘wp_footer’, ‘wp_func_jquery’);
hope can help
