Are you sure the assignment to $screen is correct as get_current_screen() seems to always return null.

		if ( 'settings_page_tabify-edit-screen' != $screen->base ) {
			return;

The parameter $posttype is not used and could be removed.

The constant WPSEO_PATH was not found. Maybe you did not declare it correctly or list all dependencies?

			include_once WPSEO_PATH . 'admin/class-metabox.php';
