Hi, Sylvia. In trying to answer your question, I came upon a question myself!
First, my fans posts don't show up on my personal wall and they're not supposed to if they are only fans of the business and not friends of your personal account. They do show on my business page. So I'm not sure why; that is odd.
Now on my fan page underneath the "write something" box, I have three things you can click on that change what type of postings show. There three things are: "The Perfect Word and Fans" "Perfect Word" "Just Fans" Fan's posts show up on mine when you click on the first one or the last one.
For those I checked, almost none of the pages for people here have those three things. I did notice that The Doctor's Rx" page does, though, and several of my "Favorite Pages" businesses do, too. You can click on
mine and see what I mean. Yours doesn't have those three things either. Maybe those of you who don't are customizing your page to remove them? I don't know if that has anything to do with posts showing/not showing or not.
I know I haven't been any help, but I'm sure someone here will know the answer! They've sure helped me a lot!!
