I’m trying to install the sitemap extension but i’m getting this error
Import Error: about.json does not exist, or is invalid. Are you sure this is a Discourse Theme?
Any ideas on how i can get it uploaded please?

I think you are trying to install [Discourse Sitemap](https://meta.discourse.org/t/discourse-sitemap/40348). If so, that is a plugin, not a theme. You need to install it by following the instructions that are given here: [Install plugins on a self-hosted site](https://meta.discourse.org/t/install-plugins-in-discourse/19157).
