[Koha] Authority search results

Dear all, After an authority search I have an authority list but clicking on any of them I receive a new window with the following error: No _parse_* routine defined on this driver The link for each entry that is seen in the bottom is the folloowing .../cgi-bin/authorities/details.pl?authid= what means that there is no authid. Is it an error or a bad parametrization. Thanks, Rafael
