theme/page/product remove sidebar.

Heya,
Just looking for some help & if anyone else has had this issue & found a way to remove it from their theme.

In the inspect. Removing this code removes it from the theme/page/product. Just don’t know where it would be in the theme/wordpress.

Pastebin to the code that hides the boxes

What I’m trying to get rid off

Thank you.

P.s. Links in code won’t work (It’s a localhost server)
