[Koha] Koha error-- branchcode

[deavorj at comcast.net]

Does anyone have a suggestion how to fix this bug in our program?   I set our " branch " every morning when I first log in Koha.  Actually, we are a small private school with only one branch, but I have learned the program needs me to set the branch.  It used to work fine, but this school year we started having  problems.  As I check in books, I get a message to inform "our branch"  the book has been returned.  The branch is set, but Koha does not seem to recognize the book has been returned to our "branch".  Therefore, when I check out books, I get the  fatal error message listed below.  We have learned we can go in and edit the item in cataloging which then tells Koha the item is at our branch.  Then we can check out the item.  Of course, it takes extra time which can be a nuisance when I have a class full of young children trying to check out books all at once.  Our program did not used to have this problem.  We do not know why this bug suddenly developed this year.   Has anyone else in the Koha community had this problem?  How can we fix it? 



Thank you, 
Janet Deavor
