post_title appears as "Post TitleBlog Title"

Hi,

Interestingly, after installing this theme, the <title> of my posts appear as “Post TitleBlog Title”. The same goes for pages and tags as well – although not categories for example.

I use All in One SEO Pack, and post title format is set to: %post_title% | %blog_title%

Page title format set to: %page_title% | %blog_title%

So what I see as my post and page <title> now is, “Post TitleBlog Title | Blog Title”

I can’t figure out where %post_title% is defined either.

Can anyone give any advice here?

Thank you very very much!
