Cause
This issue occurs specifically on VIP Enterprise Gateway version 9.11.2 when the Update Settings are set to Automatic. During the login, an unexpected file-reading exception during the unpaved LiveUpdate package processing, which corrupts the active console session state and prevents template execution.
Resolution
Access the page by removing doLogin.action from the URL and press enter to force a fresh session. (Example: http://localhost:8232/vipegconsole/doLogin.action)
