Solved Config does not save

Hello,
Here is my code:

PHP:

    public function levelUp(Player $player){
        $name = $player->getName();
        $cfg = new Config(Main::getMainInstance()->getDataFolder() . "players.yml", Config::YAML);
        $beforeLevel = $cfg->getNested("players.$name.level");
        $newLvl = $beforeLevel + 1;
        $player->sendTitle("§l§aLEVEL UP!", "§l§a$beforeLevel §l§2⇛ §l§a$nouveauLvl");
        $cfg->setNested("players.$name.level", $newLvl);
        $cfg->save();
        }

The title is sended but the config is not edited (no error is logged).
Please help

 

$nouveauLvl is undefined
If it showed the title somehow without erroring, that just means that this part of the code is not being executed

 

in my code $nouveauLvl is defined just I edited it to be english (newLvl and i forgot to edit all) to post on the forum

 

PHP:

public function levelUp(Player $player){
        $name = $player->getName();
        $cfg = new Config(Main::getMainInstance()->getDataFolder() . "players.yml", Config::YAML);
        $beforeLevel = $cfg->getNested("players.$name.level");
        $newLvl = $beforeLevel + 1;
        $player->sendTitle("§l§aLEVEL UP!", "§l§a$beforeLevel §l§2⇛ §l§a$newLvl");
        $cfg->set("players.{$name}.level", $newLvl);
        $cfg->save();
        }

 

Save the config on disable

 

Why do they need to save the config onDisable even though they already saved it?

 

Never mind I didn't read the whole thread.

 

nothing too

 

Try deleting the folder before starting the server, see if it creates the folder with the config inside.

 

i do it to edit players.$name.xp and it works but idk why lvls don't works
