Dear Koha developers & users, We are using Koha 3.12.11 on Ubuntu platform. For testing purpose I added the subscription for a periodical & received issues up to July 2015, but after Dec 2014 it is continuing with Jan 2016. Koha database is not calculating & displaying the year 2015. Is there any technical issue to solve the problem, Kindly check from your end. Thanks & Regards, Venkata Narayana T Hyderabad. Telangana.
