sitemap problem
We have concern that we are using your "vantage" theme and this
http://www.personal-trainer-suche.de/sitemap_index.xml page contains the following errors:
"error on line 2 at column 6: XML declaration allowed only at the start of the document
Below is a rendering of the page up to the first error."
Any idea how can we fix this?
