Commands out of sync; you can't run this command now
A hotfix summary
The most common reason for the error commands out of sync
are special MariaDB versions which try to optimize queries with big IN()
clauses. To stop this behaviour a config var needs to be set either in
(1) the MariaDB server config, e.g. my.cnf
inside the category [mysqld]
[mysqld]
in_predicate_conversion_threshold=0
(2) or inside TYPO3 conf vars, using the database init commands
DB:

Default:
initCommands: 'SET in_predicate_conversion_threshold=0;
