Quick fix that fixed issue for me
So - considering it was having errors in jquery itself - I just upgraded jQuery... Not sure if the following will get osTicket's stamp of approval, but it works for me :)
Step1: Download compressed jQuery 1.10.2 AND compressed jQuery migrate 1.2.1 from "http://jquery.com/download/" or attached (ideally - you would only want jQuery 1.10.2 - but some of the functions osTicket utilizes have been deprecated)
Step 2: Place the files in the js folder within the base directory (jquery 1.7.2 will be there already)
Step 3: in \staff\header.inc.php - replace:
<script type="text/javascript" src="../js/jquery-1.7.2.min.js"></script>
with:
<script type="text/javascript" src="../js/jquery-1.10.2.min.js"></script>
<script type="text/javascript" src="../js/jquery-migrate-1.2.1.min.js"></script>
Step 4: in \client\header.inc.php - replace:
<script type="text/javascript" src="js/jquery-1.7.2.min.js"></script>
with:
<script type="text/javascript" src="js/jquery-1.10.2.min.js"></script>
<script type="text/javascript" src="js/jquery-migrate-1.2.1.min.js"></script>
I did some basic testing and this update does not appear to break anything - try it out if you are having the same IE issues
