I am just checking if anybody has had this issue with a 5.5 to 5.7 upgrade? The atlassian-confluence.log of the upgrade has this error. I have tried lots of different things , such as installing using the confluence account, the root account, upgrading add-ons before the upgrade and after the upgrade. Always the same error. I imagine it it is data related but don't know how to fix this issue. I have tried to do an XML backup but the database is 3.5Gb and the operation ends up trying to access the page destination=/admin/dobackup.action that causes a 404 error.
I have also tried deleting the constraints on this table only to find other constraints.
Any cluses ???
