Group content body text not showing up in group posts

Hi, I'm having a big issue where none of the "body" content within each group's posts is showing up. If a user clicks on the "edit" tab they can see what they've written in each post, but that content isn't visible to the other group members, even when they click the "Read More" link. I've checked that the body content isn't hidden; I've tried changing the format to "plain text" and other formats; and I've tried disabling the OG Field Access module, clearing the cache, and then enabling it (something a lot of people suggest doing), but nothing seems to work. I've seen where some people suggest that the CKEditor is sometimes to blame, but I don't think that's the case here. Can anyone tell me what I'm doing wrong?
