PDOException: SQLSTATE[HY000]  Access denied for user
Next Doctrine\DBAL\Driver\PDOException: SQLSTATE[HY000]  Access denied for user 'unaux_23970071'@'192.168.%' to database 'home'
What can I do?
If you can't get full permissions for the db user, then you could try and set up a db user with INSERT, SELECT, UPDATE, DELETE, CREATE, DROP and ALTER. They used to be sufficient, but I don't know if that remains so for the current c5 core.
If you need help setting up the above, you could try your ISP technical support.
