Some pages fail to fully load

I have a problem with a site, and it baffles me. Some of the pages, including the home page, fail to fully load.

Judging by the code that does load, each page gets as far as the entry-content tag and then stops. The site is otherwise functional, and in fact a number of pages work just fine.

I cannot see why some work but others don’t. Where should i start looking?

P.S. I tried disabling all the plugins, yes. No dice.
