hi we had the same problem and tracked down the issue, which is if any of the conf files are all 'empty' (say because you dont want any of the entities.conf to be used) it freaks
the fix is simple, but of course, i dont know if its a good fix
in confutils.php:204
if ($config) {
$combined = array_merge($combined, $config);
}
i imagine it would be better if it checked if its a real Array maybe isArray()?
