Blogger Trouble

For some reason today my blog header is blocking my main title and I can't seem to fix it, haaa!
Earlier today I noticed that my title had just disappeared and I thought, oh how lovely, I can get my title to show up if I take my flower background header away but as soon as I put it back up there, my title goes behind it. How do I know its behind it? because if I make my title super big it starts popping out from behind my flower picture, not good!
If anyone has ever had this problem or can give some advice I would appreciate it, thanks.
