How do i activate the addon "Platebuff" on the Blizzard nameplates

[youa]

Hey i do have a problem with my "Platebuff" ADDON, i used to run it with Tidyplate but i honestly want to come back with the blizzard nameplate, but i wanna keep the possibility to see my debuff above the ennemy nameplate and BIG icons like sheep/fear/iceblock on ennemy nameplates too.
My problem is when i disable tidyplate addon, "Platebuff" starts to not show anything.

Here the result i want:

You need to enable class coloured nameplates somewhere in the interface settings, only worksf or pvp
