Couldn't access Portal
SA-34862
Summary
The users on IE with compatibility view turned on see this message when they attempt to access a Pega 7.2.1 application.
Error Messages
"You're using an unsupported browser. Pega 7 uses the latest web technology and your browser doesn't support those technologies. Please update to Chrome, Safari, Firefox or Internet Explorer (9 or greater)."
Steps to Reproduce
Attempt to use Pega 7.2.1 application with IE running in compatibility view.
Root Cause
Using a modern browser newer than IE 8 (such as 9, 10, 11), in compatibility view turned on the user agent string actually mimics IE 7, and thus Pega 7.2.1 fails to identify your browser as something newer than IE 8.
Resolution
The best solution is to eliminate the business need to use compatibility view. Enterprise mode offers the ability to only run on certain sites at a more granular level than what compatibility view offers.
