I happened to make a change to some alias via an SQL command to make a mass change. Now the iRedAdmin page for user details generates an internal server error. I fixed/returned all the entries to previous but still unable to use the user details at //<webaddress>/iredadmin/profile/user/general/<username>@<domain>

The log file shows the following:
Traceback (most recent call last):

Any ideas what could be wrong?
