Getting a semi-blank page after logging into WEM Framework with no options (sites or application) to choose from.

In the HTTP request/response headers of this login request, non-200 response is observed when making a REST call for the user's information.

For example:

#1 500 Internal Server Error

----------------------------------------------------------
http://hostname:port/sites/REST/users/fwadmin

Another possible symptom is that when making the REST call - http://hostname:port/sites/REST/users/fwadmin - directly in a browser, the following error is observed in futuretense.txt/sites.log:

#2 403 Forbidden

----------------------------------------------------------

Directly hitting the REST URLs in browser on LB or Web Server returns 403 as well, but the REST requests work on application server directly.

Changes

Possible changes:

#1 The environment in question was just upgraded from 7.5.x to 7.6.2 and WEM was installed during this upgrade.

#2 The environment was configured to access via a LB or Web Server.
