I have used the free version of the sitemap generator and there are two errors in the code which make the file unusable:
<urlset xsi:schemaLocation="[external links are visible to admins only] [external links are visible to admins only]" xmlns:xsi="[external links are visible to admins only]" xmlns="[external links are visible to admins only]">
Specifically the bit of the line xsi:schemaLocation="[external links are visible to admins only] [external links are visible to admins only]" we believe is formatted incorrectly.
Is this a common problem? Is this problem also present on the paid version which I was considering purchasing?
