I just updated to 3.0.3 from 3.0.1 and hoped this would fix the problem. I am using a multisite network, but I suspect that is not related.
Scheduled posts are showing up as the title only. Automatic feeds to Facebook and Twitter do show the content, but when I go in to the post in the backend, the content box is empty and there is a note: There is an autosave of this post that is more recent than the version below. View the autosave.
I cannot automatically restore the post, but I can copy the post and paste it into the content box and update the post, restoring the body of the post. Is anyone else having this problem?
I read that some were having trouble with Scheduled posts not appearing at all because they needed to change a setting in their cron.php file, so I tried that (increasing the timeout), but that didn't change anything.
