AddThis is a great service – it allows robust integration with online services, e.g. Facebook, Twitter, LinkedIn, del.icio.us. What you need to do is to get your button’s code on AddThis homepage and use it in your project. Additionally you can configure the widget; you can refer to AddThis API, where you can find needed information and examples.
I renamed the ID of that div to something else, which FIXED THE PROBLEM.
Now, of course I could use a different ID of that
div but why should I be forced to do so? I’d consider this issue as a bug in AddThis; if their code creates or uses DOM elements with some
divs, they should be given unique IDs, e.g. a hash. Only this way can they be sure they can save a few ours to a person who tries to use their (REALLY NICE) feature.
