Koha 3.4 Manual

Abstract

This preference determines how much information will be sent to the user's screen when the system encounters an error. The most detail will be sent when the value level is set at 2, some detail will be sent when the value is set at 1, and only a basic error message will display when the value is set at 0. This setting is especially important when a system is new and the administration is interested in working out the bugs (errors or problems) quickly. Having detailed error messages makes quick fixes more likely in problem areas.
