@Nzagamba A few thoughts:
- I think you need to update your sitemap url in the robots file, to the new one you made on Octopus and ensure it's uploaded to your server.
- I would suggest checking all your site pages and make sure there are none that have a no-index. You can do this by viewing the source and looking in the header. Make sure that nowhere in any of your page headers is a setting stating <meta name="robots" content="noindex,nofollow">. As I understand, if Google spots this, it will flag it as noindex even if you have other pages that don't have it.
