Confluence not starting after mysql upgrade Edited

I have Confluence 7.3.1 with mysql version 5.7.27 on Linux 64 bit.

After the upgrade of mysql (from v 5.5) Confluence is no longer starting.

The error message I get is 

ERROR [Catalina-utility-1] [confluence.setup.dbcheck.MySQLChecker] checkIsolationLevel MySQL isolation level could not be read. Isolation level must be 'READ-COMMITTED'. See

When logging in to the mysql both the global and the session isolation level is READ-COMMITTED. So I dont get this error message.

I have tried to add the parameter to the connection string to, but to no avail.

The upgrade was made on error but unfortunately we didnt use it for a long time so we no longer have a backup of the one before the upgrade.. 


Anyway, after fiddling for ages with mysql, I have been able to get forward, but still I get startup errors. Does anyone have an idea what this means:

any ideas please?

Many thanks

Anyway, I was finally able to get it up and running.

It turned out I had imported the database dump with foregin key checks active, so some data had not been imported. So recreating the database with that turned off did the trick.

Hi @Johan Johansson ,

can you please provide your my.cnf file (usually to find under /etc/my.cnf) so that we can investigate further? 
Many thanks in advance.
