There was error in the overridden addons. I have modified the file in this location: templates/shaper_cuisine/sppagebuilder/addons/chef/site.php
I have changed line 24 from
$output = '<div class="sppb-addon sppb-addon-chef sppb-text-center ' . $class . '" style="background-image: url('/. JURI::base() . $image .')">';
to
$output = '<div class="sppb-addon sppb-addon-chef sppb-text-center ' . $class . '" style="background-image: url('/. JURI::base() . (is_string($image) ? $image : $image->src) .')">';
