[CentOS] BackupPC FAQ? Backups Apparently Working, but Web Interface Shows Nothing

BackuPC host is CentOS 6.2. Just one windows XP client.  SMB backups
appear to be working; there is data in the backup directory tree,
including a subdir named for the client, in which I can manually view 
individual files that have been backed up.

Now trying to use the web interface.  Apache lets me log in, but the
status screen shows nothing.  Hosts screen says:

     This status was generated at 5/14 16:50.
     Pool file system was recently at 41% (5/14 16:43), today's max is
41% (5/14 01:00) and yesterday's max was 42%.

Presumably, this means it sees the backup directory, since it accurately 
shows space available.

Still, it says 0 hosts have been backed up.

The SourceForge BackupPC Wiki says to check Selinux setup; it is disabled.

What next?  Thanks.
