Main content collapse after Joomla 3.3.4 update

Hi, after applying an 3.3.4 update my page is set to one-column view, can't fix it. Any ideas?

Can you check modules in right position, maybe just save their settings once?

Didnt help, I've tried this couple of times

Disable all modules in left position to see what you get

It's still the same, but only difference is that the whole content is presented in one column view

I think there is unclosed DIV tag in some module in left position. Can you now put only one custom HTML module in left position , create new one and set its content in HTML view to <div>TEST</div> to be sure.
