Can't add/edit fields in IP Content after migration

[Gauravk]

I have moved from 3.4.8 to IPS 4.08 and my IP Content has substantial data in old version. All moved to new one partially OK, but I am unable to edit any old fields in all database. And I am unable to add new fields in new/old database. 

Anyone faced similar issue....? Support desk has no reply for me since 48 hours, I am hoping to hear something from users now. Please help. Thanks.

This is the error that I am getting in system logs after editing/adding any fields in new IP Content. Any idea guys, what is this...?
