Theme issues [duplicate]

I’m sorry, but I am so absolutely frustrated at this point that I want to scream. I have spent ALL NIGHT on this theme and not only does it fail to present the information I tell it to, but it’s now presenting the information I tell it NOT to. My blog now has the wrong title from a page I have not even worked on or published (it is private), as well as multiple side bars going all the way down the page. Nothing is showing up correctly. My background image, my header image, my title, my featured image –nothing.

So I’m writing again. I need help very quickly. I’m not getting anywhere with this. I would appreciate feedback as soon as possible.

Thank you,
Erin
