Hi

Open a MySQL client (like phpMyAdmin if available on your host) and manually repair the tables (select them and choose "Repair" action)

Thank-you, Mistic. Your comment pointed me in the right direction.

For the benefit of those who may face a similar problem yet need additional guidance, here is how I repaired the damaged tables:

* the subsequent instructions assume that:
your piwigo site is self-hosted
your mysql (or mariadb) user name is ' username '
the name of your database is ' fotodb '
the  name of the damaged table is ' piwigo_damagedtable '

    Login to the shell
    Enter ‘mysql -u username -p fotodb
    Enter ‘show databases;’ to view all databases
    Enter ‘use fotodb;‘ to engage the database
    Enter ‘show tables;‘ to show all tables within the database
    Enter ‘check table piwigo_damagedtable;' to verify that this is the damaged table
    Correct it with ‘repair table piwigo_damagedtable;‘

The above solved the problem for me. Hopefully, it helps you as well.

Thanks for the write-up - hopefully this will help someone in the future.
