[Koha] Z3950 Misbehaviours Fixed

Tue Aug 8 23:23:19 NZST 2006

hi,
I have a trouble searching records with z39.50 search.
i read and followed what you told.
but one problem i am having is that,
i am not getting any records in z3950 search
and also as u said, the results may not be displayed but they can be found
in the
log, but i am not getting anything in the log...
so may be i am missing something or something is wrong that i am not
getting.
so please write me if you have any idea.
(I am using koha2.2.5 and npl template...)

thanks and regards.
Lalitanand.
