Is it possible for me to add a comment section or a treehole-like section to the nodebb homepage or a custom page added by nodebb-plugin-custom-pages plugin? Something like a blog comment section but within a nodebb custom page?

@baris
I use the latest version of nodebb
After a night of investigation I think it is probably a problem related to a failed database migration so I fixed it by redeploying mongodb

Usernames of Deleted Users cannot be reused (e.g: David(deleted), another David will automatically be "David 0").
Already executed db.objects.deleteOne({_username:"David"}), and cleared all caches in /admin/advanced/cache, still get "David 0" even "David 1" after David 0 is deleted
