I am having problems with the header of my blog never seeming to stay where it should, either being too high and almost off the page or being too low and covering the title of the most recent post. Everytime I view my blog it's in a different spot. When I log into my blog sometimes it goes into place and sometimes not. I have tried emptying cookies and clearing my cache but that didn't seem to do anything. I have windows 7 with explorer 9. I tried an older browser which seemed to help for a while but then the header went back to being out of place again. What do I need to do to fix this? Thank you in advance.
The blog I need help with is bluebirdhillfarm.wordpress.com.
