[Upgrade from 3.2.1 to 4.0.0 - problem, errors!]

I had ! sign in password to database. When I've remove it upgrade process has started :)

[Upgrade from 3.2.1 to 4.0.0 - problem, errors!]

Zend Opcache is installed but disabled.

[Upgrade from 3.2.1 to 4.0.0 - problem, errors!]

I've tried to upgrade Revive from 3.2.1 to 4.0.0. I've copied database to new one, copied files to new location and settings php file from "var" folder in old location to new one.
Unfortunately I'm getting list with a lot of errors.

The first three errors:

I've changed the type of database to mysqli, but it didn't help :(

PHP: 5.6.12
Mysql: 5.5.51-38.1

Have you any ideas what should I change to fix it?

Of course I've changed the database access to new one in config file :)
