WP-Likes, I-Like-This…”Like” Plugins not working!

I’ve tried using the WP-Likes plugin, but it didn’t work. Then I tried the I-Like-This plugin, but it didn’t work either. None of the available “Like Button” plugins are working for me, and I don’t know why!

What I mean by it doesn’t work is that: the “like” image dims, but it doesn’t reveal “You like this post” or “10 People like this post” or whatever else it should be.

I have no idea what’s wrong );
