[Koha] Database problems with Koha2.2

[T & J Kotula]

Hi,

I seem to have a problem with the Koha database. When I search (via 
Catalogue->Search) for a word say 'word', I get a listing of books with 
the title, author, publisher, year, number of pages, etc, etc, exactly 
the way I would have expected. However when I click on any of these 
titles, MARCdetail.pl does not bring **any** information, the page is 
simply blank - there are no tabs (0, 1, 2 etc) on the left-hand side, 
except the 'items' one, which is empty as well. When I click on 
'Normal', which runs detail.pl, I get all the info I would have expected.

When I click on 'Edit biblio', I get all the tabs, and all the MARC 
fields the way I have set up, except **all** fields are blank.

I suspect something funny went with the database, because my very very 
old database backup works just fine.

Upgrading from koha 2.2.1 to koha 2.2.5 had no effect. I'm running RH8.

I would really appreciate any pointers, things to try, to check etc.

Thanking you in advance.
