Hi, so 2.0.7 fixed the above menitoned "bug" that bankchil theme WPLMS-> Header menu came back to normal, ie: no "background image" option anymore.
So I managed to solve my issue by adding in the style.css file of my blankchild theme :
#title {
background: url('http://www.ygenu.com/wp-content/uploads/2016/02/yGenU-Banner2.png') no-repeat 50% 50% !important;
}
This allowed :
to add alternte/default background image in the title section
the no repeat directive allows to avoid seing he image repeated both at left and right sides when screen resolutio is higher than the actual banner width.
