I sometimes receive posts from friends through my newsfeed asking me to share etc. However the 'share' button isn't there; just 'like' and 'comment'. If I go to their wall, all their posts appear this way too. It doesn't happen all the time though and other friends don't appear to have the same problem with the post.
Why can't I 'share'? I've checked all my account and privacy settings (through a web browser and through the iPad app) and just can't see where the problem is.
Can anyone please give me some specific help? Thanks!!
