One line 13364 of legenda/style.css you will see the below
.testimonials-slider {
position: relative;
background-image: url(‘/demo/legenda/wp-content/themes/legenda/images/quote2.png’);
background-repeat: no-repeat;
background-position: 10px 20px;
}
This causes an odd SSL issue when you checkout, stating this is not a secure object and this is due to the path of /demo/legenda/wp-content/themes/legenda/images/quote2.png
If you change the CSS to the path below the issue is solved even if the file is missing.
.testimonials-slider {
position: relative;
background-image: url(‘images/quote2.png’);
background-repeat: no-repeat;
background-position: 10px 20px;
}
Thanks, hope this helps other that run into the same issue.
