The purpose of this article is to provide answers to some common questions regarding browsers automatically using IE7 document compatibility mode when accessing Portal.
Q: How do I know if my browser is using IE7 document compatibility mode?
A: In Internet Explorer:
Note that, although a meta tag might be present in Firefox or Chrome indicating that they are emulating IE7 through document compatibility mode, these browsers do not support IE document compatibility mode and, therefore, do not enforce this meta tag.
Q: Why does the browser use IE7 document compatibility mode?
A: When using Portal, Appian automatically uses IE7 document mode because Portal is not compatible with newer document modes.
Q: Which browsers are compatible with Appian?
A: A full list of compatible browsers can be found in the system requirements documentation
Q: How do I prevent my browser from using IE7 document compatibility mode?
A: Update the applications to use Tempo/Sites 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.
This article applies to all versions of Appian using Portal.
