Ok so basically I have been given this one task to manage the admin side for a website that used Magento 2. But then, I have encountered some problem with the reindexing. I have been searching about it for days. The problem here is i dont even know where Magento 2 is being installed because i only have admin access. Is there any way to reindex on different computer? Im still new to this can any of you help me?
No, as an admin user you are not allowed to re-index from the backend (admin panel) when in production mode, since Magento 2.x. versions. You are allowed to re-index only from the shell / cli using magento CLI commands or by configuring cron jobs for the respective indexers.
bin/magento indexer:reindex [indexer]
If you want to have the reindexing feature available for admin users then ask your development team to install the respective extensions, which enables this feature for admin users.
Hope this helps.
Note: am not affiliated to the extension i recommended.
