Blank sitemap (no stylesheet) after passing to php7

We checked on the sitemap at https://www.elan42.com/sitemap_index.xml and this is loading as expected. Have you already resolved this issue?

You’re right, now it’s working.
It honestly seems to work randomly, like 33% of time.

Did this happen to anybody else ?

Most of the reported issues with the sitemap were because of plugin conflicts. Sometimes, it’s a caching issue. We are not certain if it’s the same case for you. You can check this article to know more about its possible causes: https://kb.yoast.com/kb/my-sitemap-is-blank-what-s-wrong/#blank

Closed. No further concerns.
