This was something I intentionally removed, I see now that I didn't include this in the change-log so apologies on that.
I removed this to make the experience easier for the user, not having to click a button to see who liked a post. I'm trying to include all drastic changes early in this beta before people are running this on their sites.
I guess I was mistaken about the number of people using this on a production site. This was something I advised against, but I'll try and have this plugin ready and stable asap.
Would you be happy with a setting to reintroduce the view likes button? I would prefer to have the likers show up a lot like Facebook by default, but if it turns out I'm wrong I could change this.
Sorry that you experienced some issues.
