Fix a bug with IE in our web-based software (PHP, jQuery)

We currently have a bug in our software that is causing the data retrieved from a json call to not display the results for IE users. I have spent hours trying to find a solution but can't seem to nail down the problem. I don't know if it is a problem with JSON or maybe a UTF-8 encoding issue? The problem is known to exist with IE9. (our software never worked with <=IE8 and that's ok) But some of our corporate customers only use IE. You can see the problem by going to our demo site at [login to view URL] Steps to reproduce: 1. Login 2. On the main page, just click the "Search" button at the bottom. 3. On the results page, it will display "No data in the table" in IE9, but will display the correct data in Chrome and FF. You can download our software using SVN by following the guide here: <[login to view URL]> You can also download a Ready2Run VM from [login to view URL] We need this done as soon as possible. Our software is based on PHP, MySQL, jQuery and Datatables (a jQuery plugin from [[login to view URL]][1])
