Portal for ArcGIS 10.2.2 "Unexpected token < undefined ".

[Anonymous User]

Recently I have deployed Portal for ArcGIS 10.2.2 with IWA on windows 2008R2. After login with portal administrator account, while creating a new group portal is throwing error as- "Unexpected token < undefined ". Any idea about how to resolve this issue?

What browser are you in?  If you're in Chrome, does it work in IE or Firefox?
