Edit in Excel with HFix-25833, user gets error



User has migrated from PRPC 5.5 to PRPC 6.3 SP1.

Initially they have tested DataTable "Edit in Excel" feature and add/update was working fine and delete didn't work.

For the delete to work they have installed HFix-25833 but after installing the hotfix they are getting an error repeatedly.

So,they have rolled back hotfixes HFix-7921(Disable HTTP-only cookies Requirement for Edit in Excel) and HFix-25833 and again installed HFix-7921 where the add/update worked previously.

But even after performing rollback of HFix-25833 and installing the HFix-7921, user is facing the same error.
