google says Error in Sitemap

[db1]

Now this is probably something quite easy, Goolge does not like the Sitemap produced,
Is it the +00:00 ? if so what is it?

This page contains the following errors:
error on line 8 at column 1: Extra content at the end of the document
Below is a rendering of the page up to the first error.
