I went to my hosting site’s management page and flushed cache. Seems to have fixed everything. Some details omitted earlier: when I first checked, the custom CSS for the mobile theme was missing. Fortunately, I had saved and it was easy to replace. Also, I’m running the WPtouch plugin but just using general settings (setup and devices) – not sure why, anymore, but seems like I installed it before Graphene added the mobile theme features. All seems well for now…
