is_home() and is_front_page() doesn't work

does your theme use any custom query in the template code before the widget is called?

custom queries generally need to be reset with wp_reset_postdata() or wp_reset_query() epending on the exact code of the query.

what theme are you using?

How do I know if theme use a custom query? I mean where I’m looking for that?

I’m using this paid theme

For some reason links didn’t work, here it’s
