Bad Argument #1 to 'gsub'

[..:D&G:..]

Hey, I get this error when I join the game: bad argument #! to 'gsub' (string expected, got boolean)

local mapName2 = mapName 
    for k,v in ipairs(MapTags) do 
        mapName2 = string.gsub(mapName2,v,"") --< --This line 
    end

mapName2 isn't a string. Which means the problem lies outside of the code you posted. Whatever mapName is it's not a string, and hence mapName2 isn't either.

Can't assist you if you don't supply us with enough code to help you. As Driggero said, it's not a string. If you're trying to store the name inside "mapName", it's most likely failing and returning false. Thus, the boolean.
