Issues with menu in Google Chrome

i recently updated the Beyond Expectations theme for my client’s site – lost all of my side column content and now the primary menu does not display in Google Chrome properly (no black background so unable to see the menu) and no menu displays at all on smart phone in Safari. Menu does display properly in firefox, Edge and IE. please help resolve this issue as ski season is almost here and it is imperative that the site menu functions properly in Chrome and Safari.
