About page information Data problems

Some of your tables have problems with their auto_increment values which
may lead to data loss.

*You should not ignore this warning.*

The problem is that InnoDB does not keep auto_increment across SQL server
restarts (it is only set in memory). So on server startup the
auto_increment values are set to max(table.id)+1.

To know how to avoid this problem see the related wiki page: DBMS auto
increment fix <https://wiki.koha-community.org/wiki/DBMS_auto_increment_fix>

You are missing the <template_cache_dir> entry in your koha-conf.xml file.
That will bring a performance boost to enable it.
