Also a better way to catch all these is probably:

local TEXTURE = "Interface\\AddOns\\EVUI\\FrameBackground"
local UnitFrames = {
    PlayerFrame,
    PetFrame,
    TargetFrame,
    TargetFrameToT,
    FocusFrame,
    FocusFrameToT,
    PartyMemberFrame1,
    PartyMemberFrame2,
    PartyMemberFrame3,
    PartyMemberFrame4,
}
local UnitFrameRegions = {
    "healthBar",
    "myHealPredictionBar",
    "otherHealPredictionBar",
    "healAbsorbBar",
    "totalAbsorbBar",
    "manaBar",
    "myManaCostPredictionBar",
    "spellbar",
}
local OtherStatusBars = {
    CastingBarFrame,
    MirrorTimer1StatusBar,
    MirrorTimer2StatusBar,
    MirrorTimer3StatusBar,
}
for _, frame in next, UnitFrames do
    for _, region in next, UnitFrameRegions do
        local bar = frame[region]
        if bar and bar.SetStatusBarTexture then
            bar:SetStatusBarTexture(TEXTURE)
            bar:GetStatusBarTexture():SetHorizTile(true)
        elseif bar and bar.SetTexture then
            bar:SetTexture(TEXTURE)
            bar:SetHorizTile(true)
        end
    end
end
for _, bar in next, OtherStatusBars do
    bar:SetStatusBarTexture(TEXTURE)
    bar:GetStatusBarTexture():SetHorizTile(true)
end
