Hello,
When I use Beaver Builder in a post, I have seen that in the archive page (category, tag…) that contains that post, is applied the .fl-builder class. I dont know if it can be useful in some case, but in others can have wrong effects: For example, with Generate Press theme. You can see the discussion around this from here: https://generatepress.com/forums/topic/not-full-width-with-beaver-builder-in-blog-pages/#post-172484
What do you think?
