			0 ignored issues – show Bug introduced 2017-04-04 07:51 UTC by Report Bug Copy Issue Report The method `getExtensionNamespace()` does not exist on `AfriCC\EPP\AbstractFrame`.

This is most likely the result of a method being renamed without all references to it being renamed likewise. Loading history...
