I tried to import configurable products using csv file.
But after importing, at the front end, it is showing as the product is out of stock.
I checked the inventory of the configurable product and the associated simple products and all are showing the correct quantity and also it is mentioned as in stock.
Also I reindex data and flush magento cache also, then also it is showing out of stock.
When I visited the associated products tab in the configurable product, no product is listed there.
Please help me to solve this.
