Hello,
The icons work fine on the front-end using either of the following:
<i aria-hidden="true" class="x-icon" data-x-icon-s=""></i>
[x_icon type="thumbs-up"]
However, when I try to add them to the back-end/admin area they do not show up. How can I enable this to start working? I am trying to add it as an example in my dashboard settings, NOT the front-end.
