Hi Sharen,
No problem.
Sorry if the video started at the beginning. I tried to clip to the middle of what was relevant to do. That video is not for a WordPress site so it is a little different.

Ha, the Robots.txt you don’t need to submit or worry about. That file, if you even have one, which you don’t have to, it tells search engines what directories to scan/index or not. So the “Disallow: /wp-admin/” is telling search engines not to index your wp-admin files, which is good.
Yes, the sitemap_index.xml is the ending url you wanted to paste.

The sitemap not being HTML, more clearly that is an old reference Google still has but probably is not valid. If you check the date on that error it is from August last year.
So it looks like the only valid errors you have are the 404 not found ones. Since those sets of errors are both from Jetpack and similar urls, I’m not sure if those errors are current or just being picked up from that old August error.
See if you can clear out those errors, resubmit your sitemap and give Google some time to index all your new content from your sitemap. It may be different or even gone when you take a look after reading this reply.
