Recently installed WordPress 3.5.1 and used the default theme Twenty Twelve, added a post and insert a photo gallery (also wordpress standard), so far so good, the problem appears when I make a comment on any photo displayed when individually, a "single" of gallery shall we say, the comment is not listed in the widget (recent Comments) when in other pages, all are listed normally, i used recent comments plugins but the problem persists. I'm a few days trying to find a solution but could not. You know what can be? It would be a bug in WordPress?
Thank you all.
