[Koha] Error when returning and checking out books

[ed c]

Hello all,

On my Koha install I am receiving errors when I check in a book. The error when I have it set to debug mode I am sent to an error page that reads:


Koha error

The following fatal error has occurred:

Can't use an undefined value as an ARRAY reference at /usr/share/koha/lib/C4/ItemCirculationAlertPreference.pm line 226.

Apache	Server version: Apache/2.2.8 (Ubuntu) Server built: Mar 10 2009 18:09:05

In production mode, I get a Web site that says:

 "production mode - trapped fatal error"

The return and or check out actually does go through but obviously I can't have library staff seeing this error every time they check in or out a book. I don't remember seeing these earlier, but I am not sure. However, nothing has changed recently that could have caused this.

I did try temporarily copying the latest  ItemCirculationAlertPreference.pm from the git repository, but that didn't do anything but change the line number in the error.

Any ideas?

Edward
