Hi Hugo, I use a software called Poedit to find those problems and fix them. I am sure there are other ways to do it, but that's what I do: 1) Open the po file in Poedit. 2) Try to save the file and Poedit will start to complain about any fatal errors in the file. 3) Look at the line numbers of the errors and locate them in the editor. Normally the line number is off by 1. 4) Fix all mistakes until the po file can be saved. If you don't get any error messages upon saving try to change the preferences of the editor. I checked the Spanish OPAC po file on translate.koha-community.org and found no errors. But there is one error in the file released with 3.6.1: ...2927: number of format specifications in 'msgid' and 'msgstr' does not match 06:47:45: msgfmt: found 1 fatal error 2926: %s since %s%s %s %s %s%s I think fixing this could help your problem. Another option could be using the updated files from translate.koha-community.org. Hope this helps, Katrin -----Ursprüngliche Nachricht----- Von: koha-bounces@lists.katipo.co.nz im Auftrag von Hugo Agud Gesendet: Di 20.12.2011 01:31 An: Koha list Betreff: [Koha] question on adding new languages Hi to everybody We have already install one koha 3.6.1 into ubuntu 11.04 and after the installation we have tried to install the spanish package we are experiencing problems with the detailed view of the OPAC, while in the english version us running fine. I have revied some old post and I have seen some similar behaviour with Koha 3.4 http://lists.katipo.co.nz/public/koha/2011-June/029486.html current problem: Software error: Template process failed: file error - parse error - /home/ubuntu/koha/opac/htdocs/opac-tmpl/prog/es-ES/modules/opac-detail.tt line 652: unexpected end of input at /home/ubuntu/koha/lib/C4/Templates.pm line 125. I wish to ask you If you think that it could be the same problem I think it is... but I wish to share with you According the old mails the problem rasies from a %s missing links in the po files, we can check by our own and fix in the templates... but we need some support to identigy the problem in the .po files... any body may guide us to fix the problem and we will release the corrected files to the community Kindest Regards Hugo -- *Hugo Agud - Orex Digital * *www.orex.es* * * Director Avenida Sarriá 29 · 08029 Barcelona <http://twitter.com/OrexDigital> :<http://orexsl.blogspot.com>hugoaguda - Tel: 93 539 40 70 Fax: 93 539 33 30 hagud@orex.es · http://www.orex.es/ No imprima este mensaje a no ser que sea necesario.
