my site is http://www.gadflyonline.com/wpblog.
Another user posted a similar problem, but the solution asked for didn't work for me. I added this plug in and it isn't showing up on most of my posts, with the exception of very old posts. For example, if you go the bottom of the page on the beatles (http://www.gadflyonline.com/wpblog/?p=182) it isn't there, but the page on Isaac Stern (http://www.gadflyonline.com/wpblog/?p=14) it is. How do i get it to be in all of my posts?
I have added a separate like button, so if you see that, that is not the share plugin working.
I would appreciate any and all help! I am very new to coding and WordPress so as much detail as you can provide would be really helpful!!
