Hi Dave
I’m sorry you are having this issue. Your sub-navigation menu isn’t displaying due to a theme conflict it seems.
Often we can provide code to help set your sub-nav menu by overriding the z-index. However, your theme nests it in a way that most menus don’t.
Unfortunately, I don’t have a quick fix for this one. I tried to search for Betheme z-index to see if anyone else ran into this issue. As I’m not a paying customer, I can’t login to read the results that I found. However, it might help you. http://forum.muffingroup.com/betheme/discussion/16782/main-menu-z-index
Could you ask the theme developer for the CSS code override your sub-nav menu so that it displays over the page title and contents?
Let us know what they say.
Thanks,
Courtney
