  3. Check the "Document mode" drop down menu.

Note that, although a meta tag might be present in the Portal environment indicating an a compatibility setting in Internet Explorer, other browsers such as Firefox or Chrome should load in the default standard compliance mode.

Which browsers are compatible with Appian?

A full list of compatible browsers can be found in the system requirements documentation.

How do I prevent my browser from using IE7 document compatibility mode?

Update the applications to use Tempo or Sites environments instead of Portal. Because Portal must use IE7 document mode to run, there is no way to run it without the browser appearing to emulate IE7 through IE7 document compatibility mode.

Affected Versions

This article applies to all versions of Appian using Portal.
