It looks like you copied the wrong code. This is what you want to add to </head> tab: <script type="text/discourse-plugin" version="0.8.18"> api.onPageChange(() => { if(api.getCurrentUser() != null) { $("#logged-in-user").text(" " + api.getCurrentUser().name.split(' ')[0]); } }); </script> And place this in the After Header tab where appropriate: <h2 class="x-title">Hey<span id="logged-in-user"></span>!
