9.1.1 Hello World Block

Hi

Downgrade php version on your server to 7.4 or fix those errors by yourself like:

PHP 8 Error "Undefined property"

Yeah, you need to add property in block controller public $fileOrder; An it will look something like that: class Controller extends BlockController { public $fileOrder; // rest of methods }

(maybe adding some isset($variableName) will be required besides that, but in general tip above should fix php8 errors).
