Solved Check where an event gets cancelled

Hey there,

I didn't changed something to my BlockPlaceEvents but now I am not able to build anymore. How can I check where and why the block placing gets blocked?

So you did not do
$event->setCancelled(true);
??

true is not necessary, you can also do

PHP:

$event->setCancelled(); 

Yah but I like to put it in so he can understand
