Comment (by 10bradders10):

 To reproduce:

 1. Add Custom HTML Block
 2. Paste in code.

 {{{
 <!-- semrush siteaudit widget -->
 <div id="ssa-widget"></div>
 <script type="text/javascript">
     (function() {
         var p = "https://www.semrush.com/leadgen/static/js/widget.min.js";
         var d = document, s = d.createElement("script");
         s.src = p + "?v=" + Math.random();
         (d.head || d.body).appendChild(s);
         s.onload = function() {
             new SEMRUSH.SiteauditWidget({
                 widgetApiKey: "594049775f50e972b3ae4a2a"
             });
         }
     })();

 </script>
 <!-- /semrush siteaudit widget -->
 }}}

 or this code

 {{{
 <script
 src="https://bookme.name/js/booklikeaboss.embed.js?i=3048&h=k4ND4TCutlQuiswPPstg5wI4oBCoNMosqHka7NT19bHRzB2VnmIo4I0J9SRn"
 async></script>
 }}}

 3. Update page.

 Currently trying to confirm if this is a bug in WP, or a server issue.

 Anyone else experienced the same?

 Thanks.
