I use these two plugins:
first installed: http://wordpress.org/extend/plugins/recommend-a-friend/
(to recommend posts to friends (ajax or lightbox type of loading when click on the share link or image)
(for showing the advanced editor for comments).
When I install the second one, the first plugins feature is not working in ajax but it loads in other page. When I disable the second plugin, the first one works fine. Hope anyone will resolve this. I guess this is a JQuery conflict.
