The option Send a message and invite is not working with last release 123.

Messages are being sent with options Message only and Message if invitation is declined.

this is due to the lack of a message when inviting someone to the guild. And this is on Blizzard's side.

Modified function invitePlayer and now its working :)

function fn:invitePlayer(noInv)
local list = addon.search.inviteList
if #list==0 then return end
-- if IsInAlreadySendedList(list[1].name) then return table.remove(list, 1) end
if (DB.global.inviteType == 2 or DB.global.inviteType == 4) and not noInv then
addon.msgQueue[list[1].name] = true
if (DB.global.inviteType == 2) then
fn:sendWhisper(list[1].name)
end
elseif DB.global.inviteType == 3 and not noInv then
fn:sendWhisper(list[1].name)
end
if (DB.global.inviteType == 1 or DB.global.inviteType == 2 or DB.global.inviteType == 4) and not noInv then
debug(format("Invite: %s",list[1].name))
GuildInvite(list[1].name)
end
if not noInv or DB.global.rememberAll then
fn:rememberPlayer(list[1].name)
local data = fn.encodeData({
type = "REMEMBER",
playerName = list[1].name
})
ChatThrottleLib:SendAddonMessage("NORMAL", FGISYNC_PREFIX_G, data, "GUILD")
end
if not noInv then
addon.searchInfo.sended()
fn.history:onSend();
end
table.remove(list, 1)
onListUpdate()
end

Justt add
if (DB.global.inviteType == 2) then
fn:sendWhisper(list[1].name)
end

there's no problem getting it to work "any way". But this solution ignores the existing logic
