So one of my Koha boxes kicked this error up: _______________________________________________________________________ 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> Problems foundCheckouts The following ids exist in both tables *issues* and *old_issues*: 18862, 18863 _____________________________________________________________________ Is the link provided in the error message still current ?? Should I follow it ?? and/or ...is the error kicked by the two items 18862 and 18863 ??
