The v2018 generates the icon like this:
<a href="#" class="dropdown-toggle" data-toggle="dropdown" aria-expanded="false">
<span class="glyphicon glyphicon-user" aria-hidden="true"></span>
</a>
As a change to generate it as it does adminLTE:
<a href="#" class="dropdown-toggle" data-toggle="dropdown" aria-expanded="true">
<img src="dist/img/user2-160x160.jpg" class="user-image" alt="User Image">
<span class="hidden-xs">Alexander Pierce</span>
</a>
I tray only for the photo this form:
client scripts -> Global -> Pages with header/footer -> Startup Script
remove icon user is working
$(".glyphicon-user").remove();
$(".dropdown-toggle").before('<img src="dist/img/user2-160x160.jpg" class="user-image" alt="User Image">');
No working good.
Thank you for your help.
