sitemap.xml is rendered with "×" as first line
I'm having problems with the generated sitemap.xml
When downloading the sitemap, it's generated with "×" as the first line.
This breaks the xml format, so it doens't work.
I'm using Odoo v10, recently pulled.
No custom modules are inheriting the sitemap_xml_index() method or any of the related templates.
Any ideas? Thanks!
