I'm getting a XOG error when XOGing out and attempting to XOG back in from the Clarity URL.
XOG error: Reference is not allowed in Prolog
Release : All Supported
Component : CA PPM XML OPEN GATEWAY (XOG)
XOG using UI XOG utility is not a supported feature. Xogging via the internal Clarity UI, is not supported
Use the XOG Client Software, as this is the officially supported method. The XOG Client can be downloaded from Administration->Client Downloads in Clarity.
