Bug 31143 works on a script to identify and fix these errors. Meanwhile you can find the problematic ones with SQL: select date_renewed, dateofbirth, dateenrolled, dateexpiry, lastseen, updated_on, debarred from borrowers where date_renewed = '0000-00-00' or dateexpiry = '0000-00-00' or dateenrolled = '0000-00-00' or dateofbirth = '0000-00-00' or lastseen = '0000-00-00' or updated_on = '0000-00-00' or debarred = '0000-00-00'; You need to replace them with NULL. -- You are receiving this mail because: You are watching all bug changes.
