Header image and menu disappeared in magzine basic theme

I know that this is five months old but this happened to me today as well. I was trying to put a logo in the header and now my entire menu is disappeared from my header and my sidebar has now gone to the bottom of my page. Can anyone help?

Thank you ??

I figured it out. I went in and got the header.php theme codes from one of my other sites and replaced it. All fixed.
