Hi,
I tried that but without success.
I digged up a little more and I found - inside framework/functions/ethos.php - function called x_ethos_entry_cover_background_image_style
I put that one on my functions.php and edited by putting “medium” and it looks like it is working now. Any possible problems I could run into by using this function?
function x_ethos_entry_cover_background_image_style() {
$featured_image = x_make_protocol_relative( x_get_featured_image_url('medium') );
$background_image = ( $featured_image != '' ) ? 'background-image: url(' . $featured_image . ');' : 'background-image: none;';
return $background_image;
}
