Thanks, im getting somewhere thanks to all your great help!

It is kind of working now but i am unfortunately getting errors when trying lfr, haven't had time
to test it more... but i've had a full lfr with no error aswell.

Mostly i can say that when entering Gara'jals spiritrealm i always got errors.

This is how i added it

local show = CustomFilter(auras, unit, icon, name, rank, texture, count, dtype, duration, expires, caster, spellID)
        if(show) and icon.buff then
        local _, class = UnitClass(caster)
        if class then
            local color = (CUSTOM_CLASS_COLORS or RAID_CLASS_COLORS)[class]
            if color then
                icon.border:SetBackdropBorderColor(color.r, color.g, color.b,1)
            end
        end

The error is pointing at

local _, class = UnitClass(caster)

and also this part in oUF\events.lua

eventFrame:SetScript('OnEvent', function(_, event, arg1, ...)
        local listeners = registry[event]
        if arg1 and not sharedUnitEvents[event] then
            local frames = framesForUnit[arg1]
            if frames then
                for frame in next, frames do
                    if listeners[frame] and frame:IsVisible() then
                        frame[event](frame, event, arg1, ...)
                    end
                end
            end
        else
            for frame in next, listeners do
                if frame:IsVisible() then
                    frame[event](frame, event, arg1, ...)
                end
            end
        end
    end)

Any hints on what the cause might be, because that error doesn't tell me that much im afraid
