[SATISH]

Hi,

Running Koha 16.11.11 / Package Installation/ Ubuntu 14.04 Desktop with
MySQL.
(updating from previous versions as and when the new releases are made)

 "Unable to Check-In" message is displayed for few patrons when trying
perform checkin.
Can you please help me how to fix the issue.
