147 This is an installation problem. If you are using mod_perl then
148 it appears that Apache is not running as user $Conf{BackupPCUser}.
149 If you are not using mod_perl, then most like setuid is not working
150 properly on BackupPC_Admin. Check the permissions on
151 $Conf{CgiDir}/BackupPC_Admin and look at the documentation.
