When I visit the page About Koha --- system information---, I am getting the information like data problem. Can anyone please help me how to solve this problem? 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 foundPatrons The following ids exist in both tables *borrowers* and *deletedborrowers*: 1322 Items The following ids exist in both tables *items* and *deleteditems*: 15979, 15980, 20761, 21245 Holds The following ids exist in both tables *holds* and *old_reserves*: 2, 3, 1 I will be thankful to you.
