update the link after export

Hello, I created I site using nicepage, I transferred on hosting, it works.
Now I wont to transfer it in localhost to modify it without affecting the visitors.
After download the site and the database on localhost, I updated all the configurations as I read on the guide, but the site works well except the button links, they continue to point to the plublished site. For that I used the plugin
Better Search Replace
and
Velvet Blues Aggiorna URL
But the probblem is still there.
Can you help me?
Best regards
Roberto
