I have just installed Koha 18.11. I checked out a book and while trying to check in the same item, the system prompted me the following: "the item has not been checked in due to a configuration issue in your system. You must ask an administrator to take a look at the about page and search for the data problems section". I need your help with this issue please. Thanks Luisa
