Yeah, I know and like this theme. But I think the issue might have something todo with the plugin upgrade we did a couple of weeks ago.
Now the separator is a an element you can change via filter.
It’s not that I don’t want to provide a support for you but I believe the issue comes from the the theme, due to our plugin recent update (a small change in one of the EM functions). In other words I suggest to contact theme developers first.
