I am using the latest standalone generator (I think vers 6).
When google downloaded the sitemap files, it show that there are numerous 404 errors due to improper links in the sitemap files (sitemap.xml.gz, mobile_sitemap.html.gz, and sitemap.html). The offending urls look like so:
[external links are visible to admins only]
Somehow, sitemap generator is attaching an additional [external links are visible to admins only] at the end (or in front).
Thanks for all assistance.
