PHP Fatal error: Declaration of OC\Files\Storage\Local::copyFromStorage(OCP\Files\Storage $sourceStorage, $sourceInternalPath, $targetInternalPath) must be compatible with OC\Files\Storage\Common::copyFromStorage(OCP\Files\Storage $sourceStorage, $sourceInternalPath, $targetInternalPath, $preserveMtime = false) in /home/nickv/Nextcloud/11/server/lib/private/Files/Storage/Local.php on line 43
