There is an error on IE9 with buttons.
This is the error IE9 developer tools show to me.
SCRIPT5007: Unable to get value of the property 'contains': object is null or undefined
core004.js, line 2 character 77735
The url is this: http://www.tns-global.es/actualidad/noticias/news-for-growth-n%C2%BA4-editorial(358)/
can you help me??
If you make an empty page with just the AddThis buttons on it are you seeing the same error?
