This is a very minor issue, but I added it for completeness of problems I found with PayPlans 4.0.2

Payplans is set to display a Font Awesome icon on the dashboard for small devices.

<i class="fa fa-file-text-o t-sm-visible"></i>

However, fa-file-text-o is not a standard font awesome icon and hence displays as an open square.

The code should either be updated to show a valid font awesome icon or removed.
