Hi.
I am trying to install concrete5 ver 5.7.3.1
It passed all the tests and is able to write to the database, I see the tables being created.(confirm by checked the database as well)
every time I try and install and it has to add the admin user it fails with the below:
seems to be some authentication issue, but I know I'm using the right ones, (done it several times now, to check )

Declaration of Concrete\Authentication\Community\Controller::getExtractor() should be compatible with Concrete\Core\Authentication\Type\OAuth\GenericOauthTypeController::getExtractor($new = false).

Trace:
