Try

PHP:

//$playercase = $sender->getPlayer()->getName(); error
$playercase = $sender->getName();


How many times I said that $sender is already an instance of Player!?

It's pointless. He only knows how to copy code.

Agreed

[When I learn plugin, someone told me] You can look up another people code if you don't know how to code, but you must understand what is that code mean.

That is @PEMapModder's quote I think... XD

$this->solution->closed();

$Xenturio = $event->getPlayer()
$Xenturioname = $Xenturio->getName()
$Xenturio->sendMeassage("Tell that to a staff, " . $Xenturioname . "!!!");
Lets see who can help me spot the error... XD

it easy (; <==

Of course it is easy...
