Cant click on the post, user profile, date and comments are not showing

Theme developer doesnt support payed theme anymore, it’s pity but reality. I love the theme and doesnt want to switch to something else.
Unfortunately, I run into some troubles and ask for help to solve them.

Normally you should be able to click on the post entry, have a date of publication, see tags and comments, like here: http://madbunny.us/vixen/demo/all/dark/vixen-blog/ (demo version of theme)

In my case, the blog post looks dead, impossible to click on the post entry, see when it was published, the author of the post, add comments, see tags, related posts etc. Here is the link: http://www.publicdifferent.com/blog/

When I click “Preview” it looks perfect, but awful when “Published”.

I checked theme preferences and block settings, it looks ok (publish comments – yes, etc).

What is wrong and where to find the bug?

Help is more than appreciated.
