I wanted to delete all migration modules because of that I use
drush config-delete migrate_plus.migration.ID
After that, I create a new migration module and enable it with
drush en migrate_NAME
and rebuild the cache. I look at the status table with
but the table shows no migration. If I enable the migration again I get the message "Already enabled". When I try to import something I get the message "No migrations found". Does anyone have any idea why this might be?
