The menu looks okay in the 2014 theme. I know it wasn’t the upgrade to 4.0 though, as I only upgraded to 4.0 about 3 days ago, and the menu was messed up before that.
I bought the template through Godaddy’s partnership with template monster, so perhaps I should pester them about “fixing” their template? What’s weird is it looks fine in every browser but Chrome and Chrome mobile, so I’m not sure what’s up.
