IE 9 browser compatibility issue

Dear Sir / Madam,

We have developed a web portal using appzillon 3.5.12 and deployed the same on Jboss web server.
To make it compatible with Internet explorer, we have added the following code in appzillon.jsp:

<meta http-equiv = "X-UA-Compatible" content="IE=EmulateIE9"/>

After deployment, page is loaded only after launching the developer tools in the IE (i.e on pushing F12 button).
We observed that some of the appzillon scripts like owasp.js, jquery.js etc. are using "console.warn" / "console.log" statements in the code.
Console object is activated only after launching developer tools otherwise it is throwing an error and the page is not loaded.

Please provide a solution for this issue.
Dear Sai,

Thanks for bringing this to our notice. We will address this as soon as possible. Till that time please use below shim to get rid of the isssue.

if (!window.console) {window.console = {};}
if (!console.log) {console.log = function() {};}
