#1 Updated by Etienne Massip almost 10 years ago

Looks a lot like #12026-3, did you migrate from Trac too?

#2 Updated by Michael F almost 10 years ago

Yes, i have migrated from Trac too. Manually set (SQL) all fielfs with date (created_on and updated_on) from '0000-00-00 00:00:00' to a valid value solved problem :)
UPDATE `wiki_contents` set `updated_on`='2010-12-31 23:59:59' where `updated_on`='0000-00-00 00:00:00'


But i think, that for null as date or wrong date must be showed correct error message.
