I am developing a online store with Magento 2.2.2. I have to import customer from old site. The problem i am facing, in magento 2.2.2 customer grid is empty, even not a single grid title is showing (screenshot attached).
I can add new customer successfully but new one also not showing in grid. If i try again with same email then showing customer already exists.
Solution I tried:
php bin/magento indexer:reindex
php bin/magento indexer:reindex customer_grid
php bin/magento cache:clean
php bin/magento cache:flush
Any one can help me? Did I miss anything? Is there any way that I can solve this problem?
