Have you executed the upgrade script sql-update-3.2.10_to_4.0.0-mysql.sh?

No

Run it to solve your issue.

It`s no help.
I use PostgreSQL and start sql-update-3.2.10_to_4.0.0.sh.
Need start sql-update-3.0.0-to-combined.sh ?

Show your log and your config file.

./sql-update-3.2.10_to_4.0.0.sh

Converting c_mail from VARCHAR(255) to TEXT in Contacts quick tables
?????? ???????????? sogo:
ALTER TABLE sogo_quick_contact ALTER COLUMN c_mail TYPE TEXT;
ALTER TABLE sogo_quick_contact ADD c_hascertificate INT4 DEFAULT 0;
