Sorry for the trouble, guys.
Y’all must be running old versions of osTicket Awesome. That mistake was fixed in 1.15.3 and higher.
In any event, the best practice is to remove any absolute links. If you hard coded it to your own server, that’s probably fine. But here is the fool-proof solution:
<script type="text/javascript" language="javascript" src="/osta/js/jfontsize/jstorage.js"></script>
<script type="text/javascript" language="javascript" src="/osta/js/jfontsize/jquery.jfontsize-2.0.js"></script>
Have a good day!
