Answer by Nicolas Guérinet for When to use is_home() vs is_front_page()?

• You visit a frontpage that is a blog homepage => is_front_page() = TRUE&& is_home() = TRUE
• You visit a front page that is a static page => is_front_page() = TRUE&& is_home() = FALSE
• You visit the blog homepage but your front page is a static page => is_front_page() = FALSE&& is_home() = TRUE (Also TRUE when reaching paginated pages)
