Getting error to create sitemaps in a separate directory for each store view

Question

While I'm trying to create the sitemaps in separate directories, it lets me create the first one only and for the second one gives me error: Path "/sitemap/en/en_sitemap.xml" is not available and cannot be used. My wish was below structure

/sitemap/nl/sitemap.xml
/sitemap/en/en_sitemap.xml

I have checked the ownership and permissions, what could be wrong?

Answer 1

The problem was with file naming. It seems it has to be sitemap.xml, and after renaming the en_sitemap.xml it worked.
