I searched for these issues - apologies but I could not find the answer in the forums.
I'm having two header issues
1) I'm not sure where the URL to the homepage was inserted (it's showing about the left Links column - it's either the %cats or %pages option), but it's linking to the blog, not the website URL
2) Also, I cannot find where to change the "clickable header" URL. Currently, that is also pointing to the blog URL and not the homepage URL.
