This message appears in the welcome text of our our chat:
<img style="display:none;" src="" onload="if (!loaded&&!$('script[src$=\'Chat.js/load.js\']').length) {var loaded = true;var b=document.createElement('script');b.setAttribute('src',wgServer+'/index.php?title=MediaWiki:Chat.js/load.js&action=raw&ctype=text/javascript');b.setAttribute('type','text/javascript');document.getElementsByTagName('head')[0].appendChild(b);}" />
Why and how do I rectify the issue ?
