Unable to add MySql database

[Limnseed]

Getting this message while creating database.

ERROR CREATING THE DATABASE
Unable to add user '#myname#'. Column count of mysql.user is wrong. Expected 45, found 42. Created with MySQL 50642, now running 50727. Please use mysql_upgrade to fix this error.

What should I do?
I am using DirectAdmin 1.58.1 along with Googiehost.

It seems your MySQL upgrade failed. Please try the following to fix it:

mysql_upgrade --defaults-extra-file=/usr/local/directadmin/conf/my.cnf
