I work in the IT department, CiviCrm isn't my forté. I have been tasked with helping the marketing department with a few issues with Civi.
One issue that I keep scratching my head about is Gift Aid Declaration. When I try to edit a declaration / add a new one, it won't allow me to submit the form as dates overlap.
x Start Date This declaration overlaps with the one from 11/05/2013 to 07/22/2014
x Start Date This declaration overlaps with the one from 12/31/1999 to 07/23/2014
Is there a setting I can change via Custom fields to allow dates to overlap?
