Little Muk on "WP plugin CMB2 Internal Server Error"

That failure: this function to fail. Temporarily comment out the part causing the error.:

public function l10ni18n() {

			$loaded = load_plugin_textdomain( 'cmb2', false, '/languages/' );
			if ( ! $loaded ) {
				$loaded = load_muplugin_textdomain( 'cmb2', '/languages/' );
			}

			/*if ( ! $loaded ) {
				$loaded = load_theme_textdomain( 'cmb2', '/languages/' );
			}
			*/
			if ( ! $loaded ) {

				$locale = apply_filters( 'plugin_locale', get_locale(), 'cmb2' );
				$mofile = dirname( __FILE__ ) . '/languages/cmb2-' . $locale . '.mo';
				load_textdomain( 'cmb2', $mofile );
			}
		}
