I made the changes to a dev install some time ago. I exported the child style. Now I did a test upgrade of my site to XF2.2, installed the style and imported the xml for the child style. On the test upgrade site the node icons for subforums display. But the node icons for main forums do not display. I only see an empty block. the page has this code: <span_class="node-icon" aria-hidden="true">
Is this aria-hidden the cause? If so, do you know where to address this?
