for i,v in pairs(messagesFolder:GetChildren()) do
	print(v.content.Value)
	StringChatLog = StringChatLog .. [[
	; ]]
	..v.Name .. [[
	Author: ]] ..v:WaitForChild("author").Value ..[[
	Content: ]] ..v.content.Value -- error apearing here
end

why sometimes my topics doesn’t appears in “last” tab?

My theory is that StringChatLog is nil, did you check if all the other variables are nil?
