VQadmin problem

Hello,

I'm running Vpopmail 5.4.7, with MySQL and Apache 2. I am experiencing a
particularly frustrating problem with VQadmin -- it is able to recognize
that a domain exists, it is able to fetch a list of the users within
that domain, but it is unable to fetch anything else, including the data
for the domain, the data for any given user, etc. It crashes when trying
to add a user. I've tried VQadmin versions 2.3.2 (vanilla) and 2.3.6
(came with qmailrocks). Nothing is being output to the Apache error log,
or syslog.

Please let me know if there is any other information that would be
useful in sorting out this problem, as well as anything else I can do.

Thanks!
