Slider overlapping menu bar after rollback

Hello everyone,

I just suffered something horrible that only a rollback could fix. Everything returned to normal, apart from content on my website is now overlapping the menu bar on the home page and archive pages.

We do have a web developer who I’m sure can fix this, however rather than bother him, can anyone tell me how to fix this? There should be a leaderbar inserted between the slider and the menu too, but that seems to have disappeared entirely. What part of the Editor view should I go to, to insert an inch or so gap and reinsert the leaderbar if necessary?
