Hi, Something is providing you with an invalid date. Are you using the current version of Koha? I did a google search and found the following page: http://irc.koha-community.org/irclog/koha/2011-12-02 Search for Date::Calc::Add_Delta_Days() in that page and you will see someone had a similar problem.
