So weird. I’m not sure how I got it to work again, but it’s back. I thought maybe it had something to do with the WP Retina 2x plug-in as it seemed to come back when I deactivated that. But then I put it back and no problem still (made sure to clear the cache). Hmmm. Well, at least now people can navigate my site as intended!
I just visited to your site and its working fine. There may be some conflict in the plugins with WP retina 2x so you may deactivate the plugins and anyway great that your site is working fine.
Thanks for the tip. I still haven’t quite figured out how to use the Retina capabilities. I’ll disable it for now. Not sure which plugin might be conflicting. In the process of creating a child theme I got the menu working again which was a huge relief.
