Comment (by Otto42):

 Replying to [comment:4 jbx]:
 > But I checked their template php file, and they have the `have_posts()`
 check, so I can't figure what could be the issue.

 This is still a duplicate of the other ticket. The existence of a
 `have_posts()` check does not a proper Loop make.

 "The Loop" specifically exists when `the_post()` is called. This sets up
 the various globals. Without such a call, then the globals aren't set, and
 so you are calling `the_content()` outside of a proper Loop.

 Putting the results of `get_post()` into a `global $post` isn't good
 enough to make a Loop.

 In any case, being tracked in the other ticket.
