Hi romolo
There was a syntax error in this file /templates/uber/acm/cta/tmpl/style-3.php
$ctaBackground = 'background-image: url(" '.$ctaImg.' "); background-attachment: fixed; background-repeat: no-repeat; background-size: cover;';
I corrected it as
$ctaBackground = 'background-image: url('.$ctaImg.'); background-attachment: fixed; background-repeat: no-repeat; background-size: cover;';
It works fine now.
P.S.
This forum should provide support for active members only , you are using a commercial template ( UBER ) to continue to receive support and update your website extensions , i recommend to renew your membership.
