My datastore script is not working, not ingame and not in studio (with api on)?

Try this (script to put in ServerScriptService)

    ["DoMessages?"] = true; --[[ <-- Reminder of saving/loading ]]
    ["IsAnObby?"] = false; --[[ <-- Respawns the character to fix loading ]]
    saveType = {
        ["Normal?"] = true; --[[ <-- Set to false if other ]]
        ["SavingList?"] = { --[[ <-- Specific wanted admins ]]
            ["DoIt?"] = false;
            theList = {
                "Name1";
                "Name2";
                "Name3"
            }
        };
        ["BestFriends?"] = false; --[[ <-- Best friends of your's only. ]]
        ["Friends?"] = false; --[[ <-- Friends of your's only. ]]
        ["OwnerOnly?"] = false; --[[ <-- Only you have saving stats ]]
        ["Gamepass?"] = { --[[ <-- Needs a gamepass to save ]]
            ["DoIt?"] = false;
            ["GamepassId"] = 000000
        };
        ["Asset/Item?"] = { --[[ Such as a T-Shirt ]]
            ["DoIt?"] = false;
            ["AssetId"] = 000000
        }
    };
}

If this won't work make sure that api is ON
