[Koha] support for koha in other languages

Hi all, as I've been telling, my work in the Koha translation is in development. But I've noticed some bugs in certain templates. For instance: in the parameters section i can't go into the first option, Library Branches, i click on it, but get an error, I know that is for the translated template, so if I replace it again with the one in English, it works. But I edited again the same template ONLY CHANGING JUST A LETTER IN SOME TEXT and still get the same error. If someone please could give me a pointer, I'll appreciate it. I'll also checkout the other translations, 'fr' and 'pl' to know what to do... Thanks Cheers. J0se
