Dear all, I have recently installed Koha LMS for my library. I have encountered various errors when entering the records to the system. I managed to solve some problems but I sitll have one which I have tried to solve but in vain. When I save the record of an item entred into the system, the system displays the following message: The following fatal error has occurred: Tag " " is not a valid tag. at /usr/share/koha/lib/C4/Biblio.pm line 2036 Apache Server version: Apache/2.2.12 (Ubuntu) Server built: Nov 12 2009 22:49:46 Koha 3.00.05.003 Koha DB 3.0005003 MySQL mysql Ver 14.14 Distrib 5.1.37, for debian-linux-gnu (i486) using EditLine wrapper OS Linux kohasvr 2.6.31-19-generic #56-Ubuntu SMP Thu Jan 28 01:26:53 UTC 2010 i686 Perl 5.010000 Will you kindly help me to fix this problem so that I continue entering records in my system.
