If you have a Fan Page change the settings so that all the wall posts are shown.
Follow my easy steps below
This is how mine looks as you can see that my wall shows all the posts made on my wall regardless who makes them.
When you first publish your Fan Page it will show like this (thank you to Andrea Pittam for allowing us to use her page). What happens here then is that if you want to see the comments of your customers you will need to click on the just others tab to see them and to be honest I’m lazy I won’t bother!
So set it to show the posts like mine by going into edit settings, then choose wall settings and change them so they look like this.
