This looks like a good hint, I had to change it a bit

#text-5, #text-3, #av_latest_posts_widget-3, #text-15, #text-17, #av_latest_posts_widget-4, #text-14, #text-18, #av_latest_posts_widget-5, #text-16, #text-7, #archives-2 {
    border: none;
    margin: 0em;
}

It’s a bit long, but it seems working.
Thank you

Thanks, but that removes every Widget border in the site, it’s not what I mean and can be easily done from theme configuration too.

I want the borders for my sidebar Widgets, and in the html of my pages when I specify “Widget” as class.
The ones that shouldn’t be there, and weren’t there before, are the ones in the body:

This is how it was looking before:

There SHOULDN’T be borders in the body of my Homepage!
