You need do indexing for design flat table.

Do indexing using the command line

php bin/magento indexer:reindex design_config_grid

Also check database table theme

Ensure the theme folders should available at system respect to that table list

  • i checked theme folders and also run the commande but no result Commented Sep 19, 2018 at 7:58
