Hi, a new theme appeared in my site, it’s called “Foundation”, I never installed it, do you know something about that ? Thanks !

I believe Foundation is the new name for the Default theme and will have replaced it if you hadn’t modified Default. @jordan.vidrine can correct me if I’m wrong.

至少在这个阶段，它们仍然应该被隐藏
