Something is not indexhibit friendly on some servers. If you want to make it work, you'll have to edit the defaults.php file (in the ndxz-studio folder).
Find the line:
$base = 'http://' . $_SERVER['HTTP_HOST'] . $self . '/';
and just remove the $self
so you must have something like this:
$base = 'http://' . $_SERVER['HTTP_HOST'] . '/';
it should work just fine.
thanks to Vaska, he's the man ;)
