|| Magento2 reindex on local server
You can’t reindex from admin web. you have to reindex from command line
- go to command line from magento2 installation root directory
php bin/magento indexer:reindex
if you got any error like ‘php’ is not recognized as an internal or external command,
so you need to Add E:\xampp\php to your PATH Environment Variable.
E:\xampp\htdocs\magento2>php bin/magento indexer:reindex
