I recently upgraded to ver 6.x and the ZPH queue tree no longer working.
How to get it running again? what rule?

ZPH queue tree? Please provide more details and it would also be helpful to post your configuration with /export

ZPH for squid?
if that's the case it translates to packets being marked with dscp.

up ++

/ip firewall mangle add action=mark-packet chain=prerouting disabled=no dscp=12 new-packet-mark=proxy-hit passthrough=no comment="Iphobos.com / "
