remove /category/ in url

Hello,

I would like to use wordpress like a CMS but i don’t know how remove /category/ in url…

I found plugin (top level cat) which does this some month ago but not with the 2.7 version.

Moreover, i had looked this website : https://www.themadhat.com/blogging/remove-category-base-wordpress or this https://bloggerholic.com/wordpress/how-to-remove-category-base-from-permalinks-45.htm

But i don’t make a success to have what i want, remove /category/ of my url…

Could you help me please?

Thanks a lot,
