[Koha] Opac issue after upgrade to 18.1

[Hugo Páscoa]

Hi koha community

I am using debian 9 with mariadb and upgraded to 18.11.

The OPAC can query the database and returns the total number of results.

But it doesnt shows biblio description, like title, autor, etc,...

However it shows in place of every biblio description "place hold", "save
to lists" and "Add to your card". And this options actualy work if use any.

Can you please advice?
Thanks in advance
