I'm upgrading to Beta 6 and following these steps https://discuss.flarum.org/d/697-devflarum-sandbox-server but then once it was done I get this error:
"Deprecated: The third argument to Zend\Stratigility\MiddlewarePipe() ($out) will be required starting with Stratigility version 2; please see https://docs.zendframework.com/zend-stratigility/migration/to-v2/ for more details on how to update your application to remove this message. in C:\wamp\www\flarum\vendor\zendframework\zend-stratigility\src\MiddlewarePipe.php on line 101"
What do I do?
Thanks.
