Current Viart (new) Site menu requires a change in php.ini of PHP 5.2:
 
allow_call_time_pass_reference = On
 
This has been deprecated and may be removed from future releases of PHP. This has caused problems with adding new Site Menus until I turned this value on inside php.ini.
 
 

This can be fixed by changing the file block_navigation.php
 
from this:
 
build_menu(&$items, $subitem_id, $depth_level);
 
to:
 
build_menu($items, $subitem_id, $depth_level);

Hello,
 
Yes, you are right and this fix will be available with our nearest release.
 
Thanks,
