What layout are you using?
Anyway open the layouts .lua file in a text editor and locate the part where it says (most likely at the bottom)
Code:
local party = oUF:Spawn("header", "oUF_Party")
and comment it out by inserting two -- in front of the code or remove it completely, this includes any extra lines with settings that is in there. since you didn't tell what layout you are using it's hard to say.
Code:
This is not commented out
--but this is
this is not
--[ this
is also
commented out ]]--
There is also a raid header which would look something like this
Code:
local raid = oUF:Spawn("header", "oUF_Raid")
So for a sample layout it would look like this when you are done
Code:
...
--[[ local party = oUF:Spawn("header", "oUF_Party")
party:SetPoint(x,y,z,v)
party:SetManyAttributes(
"showParty", true,
"yOffset", -100,
"xOffset", -40,
"maxColumns", 2,
"unitsPerColumn", 2,
"columnAnchorPoint", "LEFT",
"columnSpacing", 40,
)
party:Show()
]]--
