Dear All I am trying to generate barcodes from Koha (Using Generate Barcodes Link at Koha Admin>> Barcode Generator>> Generate Barcodes). But I always find an error given below in intranet-errorlog file of Apache: [Wed Feb 14 13:14:40 2007] [error] [client 127.0.0.1] Premature end of script headers: barcodesGenerator.pl, referer: http://intranet/cgi-bin/koha/barcodes/barcodes.pl [Wed Feb 14 13:14:40 2007] [error] [client 127.0.0.1] Can't locate PDF/API2/PDF/Utils.pm in @INC (@INC contains: c:/usr/koha227/intranet/modules C:/usr/site/lib C:/usr/lib .) at C:/usr/koha227/intranet/cgi-bin/koha/barcodes/barcodesGenerator.pl line 33., referer: http://intranet/cgi-bin/koha/barcodes/barcodes.pl [Wed Feb 14 13:14:40 2007] [error] [client 127.0.0.1] BEGIN failed--compilation aborted at C:/usr/koha227/intranet/cgi-bin/koha/barcodes/barcodesGenerator.pl line 33., referer: http://intranet/cgi-bin/koha/barcodes/barcodes.pl I have installed PDF-API2-0.57 but the error is still there. What should i do? Also, I am unable to add new authorities. I always find a javasript error on the page. Note: I am using Koha 227 on Windows XP. Ata
