Estimados/as: Estimados testeando la versión 20.05 migrada de una version 17.05. Al intentar exportar carnets de usuarios nos salen estos errores en el log y el archivo exportado solo muestra un recuadro en rojo. El diseño que tenemos es en cm y en base al tamaño de una hoja a4. En la 17.05 anda sin inconvenientes pero en la 20.05 salen estos errores: [2021/05/17 08:45:51] [WARN] Use of uninitialized value in string eq at /usr/share/koha/intranet/cgi-bin/catalogue/MARCdetail.pl line 208.
