Every page of my blog shows what appears to be html code at the top of the page above the Atahualpa header.
On the Blog pages this is limited to the title of the blog.
On my About Us pages the code eats up over an inch of the top of the page, with content that duplicates the several paragraphs of the page.
I'd like to get rid of this. It's making my site look unprofessional.
You can see what I mean by checking the site. http://writingasaghost.com/blog/
Please help!

First make sure it isn't a plugin issue by deactivating your plugins. If the problem goes away you just start reactivating them a few at a time until the issue goes away.

Thank you so much. That solved the problem!
