Some of JasperReports Server pages are not displayed in IE11

Issue

One of the users experienced issue where Manage->Users page was always blank in IE11 browser

Cause

The issue may not be specific to the Users page only, it may happen for different pages of the application. In general such issue in IE browsers is happening because the browser is running in compatibility mode. You can check this by opening the developer tools on the page (by pressing F12), go to Emulation tab and set the Document mode to "Edge". 

You can force the Edge mode for IE by modifying the following section in /WEB-INF/decorators/decorator.jsp file on JasperReports Server: 

<!--
<meta http-equiv="X-UA-Compatible" content="IE=8"/>
-->

First uncomment this section, and then set content to "IE=Edge" instead of "IE=8". Then restart the server to apply the changes.
