Removing the line under title links

Hi,
I want to remove the line under links on the titles or the body text. I copied the code that I saw in a topic on the Shamrock Forum (here below) but it doesn’t work !

Can you help ?

Thanks you in advance.

– Sample of page where I doesn’t want to have the underline on the title and the arrows (h4 style) : https://chatila.cluster015.ovh.net/chatila.cluster015.ovh.net/works/sculptures/sculptures-03/
– The CSS code that I copied :
body .entry-content a:not(.more-link) {
background: none;
text-shadow: none;
}
body .entry-content a:not(.more-link):hover { text-decoration: underline; }
