I use WPML with the languages per Domain settings, so Yoast creates a sitemap for my root domain.com and for xx.domain.com. So far I thought when configuring Cache Preload in W3TC, that putting “/sitemap\_index.xml” (so a relative path) in the Sitemap URL field will cover both of my sitemaps. But it seems that I need to use an absolute URL, so a combined Sitemap of both languages seems to be needed. Is that true, and if so, does any1 know how can I handle this? Can I generate a combined sitemap with Yoast maybe or is there another plugin that doesn’t interfere?
Thanks and best regards,
