Yes, we were able to resolve it.
Try first identifying if you are facing the same problem or not. So login into your portal schema on sqlplus, and see if you get any rows for the following:
select * from wwc_version$;
If you do not see any rows, then it means that the portal user is not granted Select on wwc_version$. if that is the case, then grant it. and then try to run ptlconfig again.
hope that helps.
