I did notice that Brent’s sitemap has an extra address in the “urlset” field. I don’t know if that’s meaningful, but just comparing it to my own (or the Realmac one, for example - https://www.realmacsoftware.com/sitemap.xml).
The latter has: <urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">
Like I said, I don’t know if that matters or not. I just use the default sitemap in RW, I don’t know if Brent is using one generated from another tool?
I just recently uploaded a new one which I used a web service to generate for me, and it cleared the Google test.
The sitemap in my dropbox I had went to the trouble of adding href lang tags and for some reason was giving me the above error after the google test.
So now I got a sitemap that passes the test but I’m also wanting to define languages for my website and I apparently am out of my league on that.
