I've created a business page and a profile for myself, but when I post on someone else's community page wall the post is only visible to my friends. The posts are not visible if I log out either. I've tried posting with my personal profile, and as my business page and I've tried things like @-tagging and liking the pages I'm trying to post on. How do you do this? It's really frustrating, since I can see other people posting on the walls I'm trying to post myself.
This sounds like a security settings issue. It could be that your post security is set to friends only, or that the page owner has their page security set that way.
