Read more in Visual Editor not working

Hi there,

I add in the read-more tag into the Visual Editor in the Page Builder but though I can see it there, it is not working.

I added this into my functions.php page as suggested

function theme_child_fix_more(){
if(is_front_page()) {
global $more;
$more = 0;
}
}
add_action(‘template_redirect’, ‘theme_child_fix_more’);

but i can’t get it to work.

Any ideas?

Thanks,
Talia
