Hi, all!
A friend of min is running CQRLOG 2.5.2 on Xubuntu 18.04.
After an update he got the following error message in mysql.err. Any solution? Thanks a lot in advance!

Hej Pontus!
What did happen with update? What is the database engine version now?
Could it be that update downgraded MariaDB, or even switched to Mysql instead.
In console:
mysql --version
LIne "InnoDB: A downgrade from MariaDB 10.2.2 or later is not supported." worries me.
If you put "cqrlog.com downgrade from MariaDB" (without quotes) to Google you see that there has been similar cases in forum before. Using forum's own advanced search you cannot find them.
