I have a woocommerce site with wmpl and this glorious Seo plugin...
All works fine except the xml sitemap with one taxonomy (an attribute for products)...
This taxonomy has this name: olfactory-groups
i think that the problem here could come because of the "-"?
look the index sitemap: http://www.perfumesba.com/sitemap_index.xml
the two sitemaps for this taxonomy doesnt work (in both languages). but the other product attributes... are working perfect
