First, great plugin. And while it worked... I was recommending it to all of my clients. However, after seemingly no change, the slider (built into my theme) stopped working. I disabled the plugin, and my slider worked again. I was in touch with the theme developer and they commented:
"I think it's a plugin script error."
Would love to get this working again. In the meantime, I supposed I'll have to go back to AddThis only.
