Any example how to use and activate psr3 log in phalcon.

Hi can somebody give an example how to use Phalcon\Logger\Adapter\File as Psr\Log\LoggerInterface?

I've tried enabling phalcon.register_psr3_classes = On but the filelogger instance will fail if it is used by setLogger() returning: Argument 1 passed to EdaunRetail\Lib\PromoQuery\Logger::setLogger() must implement interface Psr\Log\LoggerInterface, instance of Phalcon\Logger\Adapter\File

What version of Phalcon are you using?
