SQLSTATE[HY000]: General error: 144 Table './statsdel_piwi2/piwi_option' is marked as crashed and last (automatic?) repair failed

Could not find the Matomo configuration file, and you are trying to access a Matomo page.
ยป You may install Matomo now
If you installed Matomo before and have some tables in your database, don't worry, you can reuse the same tables and keep your existing data.
