Henri,
First time we are reported such a problem.
Looks like I'm a guinea pig :-) Answering your questions:
A) have you tried to see source code of the MARCdetail.pl page to see if it has data?
The information is not there - so unfortunately it's not an HTML/browser bug problem. The relevant, unedited code snippet is: <div class="tabs"> <a href="javascript:active(10)">I<br>t<br>e<br>m<br>s</a> </div> <div name="0XX" id="0XX" class="tab" style="visibility:visible"> </div> <div id="1XX" class="tab"> </div>
B) Is your framework using subfields and tabs (seems yes, but just want to verify) ? And are subfield values "hidden" ?
Framework is the same for both: current (broken) and very old (working) databases. Just for the record say for a MARC field 245, subfield <a>: marc_subfields_structure.pl?op=add_form&tagfield=245&frameworkcode= the only fields I have filled in are: mandatory, koha link: biblio.title, both Texts: Title, managed in tab 0 Thanks looking into this problem tomasz kotula.
