 * I optimised my database, which also included removing orphaned data.
 * I suspect this optimisation interfered with Smart Crawl, as after that the \sitemap.
   xml returned a 404 error. Only after completely removing Smart Crawl with
    Settings/
   Data & Settings/Uninstallation settings set to Reset. After reinstallation everything
   was OK.
 * As a check, I swapped my database to the backup copy I made before the optimisation
   and confirm that Smart Crawl was in good shape and the sitemap did display correctly.

 * Hi [@antonv](https://wordpress.org/support/users/antonv/)
 * I hope you are doing good today.
 * Could you share with us the full steps you have made and what plugin you used
   to optimize your database so that we could test that on our lab site?
 * If some plugin was used what features were disabled/enabled so that we could 
   replicate this in the same way you did.
 * Kind Regards,
    Kris
