Nextcloud server: error creating admin user

hi

i installed nextcloud 13.0.0 on my ubuntu 16.4 server essentially by following the nextcloud documentation and this instruction:
https://www.modius-techblog.de/linux/nextcloud-unter-ubuntu-16-04-installieren/
Everything was fine but in the end i was not able to create the admin user threw the graphical interface on http://localhost/nextcloud. the error message is as follows:

Error while trying to create admin user: An exception occurred while executing ‘INSERT INTO oc_migrations (app,version) SELECT ?,? FROM oc_migrations WHERE app = ? AND version = ? HAVING COUNT(*) = 0’ with params [“core”, “13000Date20170705121758”, “core”, “13000Date20170705121758”]: SQLSTATE[HY000]: General error: 1665 Cannot execute statement: impossible to write to binary log since BINLOG_FORMAT = STATEMENT and at least one table uses a storage engine limited to row-based logging. InnoDB is limited to row-logging when transaction isolation level is READ COMMITTED or READ UNCOMMITTED.

Exactly the same error with fresh install on FreeBSD.

DB set up

CREATE DATABASE nextcloud;
CREATE USER 'nextcloud_admin'@'localhost' IDENTIFIED BY '<your password here>';
GRANT ALL ON nextcloud.* TO 'nextcloud_admin'@'localhost';
FLUSH PRIVILEGES;
exit

per https://ramsdenj.com/2017/06/05/nextcloud-in-a-jail-on-freebsd.html

Solution: per: https://github.com/owncloud/core/issues/16008

add “binlog-format = MIXED” to my.cnf
(on freebsd: ee /var/db/mysql/my.cnf)
restart mysql
(on freebsd: service mysql-server restart)
