BuddyPress missing 'Create Group' or 'Post' Buttons

This is a weird one I've just been informed today, I'm going to start by removing some plugins to find the culprit but just in case I'm posting here (It's a live site)

My site (airsoftnation.co.uk) doesn't show the 'Create' groups button - and in groups you can't Post.

Perhaps something silly I've missed, but I'm certain the site was fine the other day. As it's a live environment I'm not keen on making many changes so I'm going to probably put it into maintenance mode later and try any suggestions.

Many Thanks,
Graham
