AddThis

Added pinterest to services_compact, but button not showing up

I'm trying to use a limited list via the API 'services_compact' option, however it's not showing up. If I remove the services_compact option, the Pinterest button does show up and correctly parses images on the page. I also added a <meta property="og:image" /> tag in my head but that had no effect.

Is this a known issue? I haven't found any details on this specific problem.

Here's a link to the site in question (see "Share" text link in the upper right). The addthis_config object is at the bottom of the doc in the source code, but here it is anyway:

var addthis_config =
{
services_compact: 'facebook,twitter,google_plusone_share,pinterest,email',
ui_use_css: false

}

Any help is greatly appreciated.
