I have recently been pounding my head against the wall with trying to add a simple image logo to the top-bar code -
<div class="top-bar-title"> <span data-responsive-toggle="topbar-responsive" data-hide-for="medium"> <button class="menu-icon" type="button" data-toggle></button> </span> <a class="topbar-responsive-logo" href="#"><div class="title-bar-title"><img src="assets/img/CMB_logo_lt.png" alt="" /></div></a> </div>
After a lot of trial and error, I discovered that topbar img asset cannot be an svg file. I had to save my logo as a png and everything worked fine.
So I'm not sure if this is a bug or somehow I missed the documentation. I hope this helps someone.
