I found some informations about this problem in this forum, but it doesn't work.
http://www.takeacamera.com and you will see my problem :-(
I tried to modificate /wp-content/plugins/sociable/css/sociable.css as it is written in http://wordpress.org/support/topic/plugin-sociable-facebook-like-button-half-displayed?replies=11
It look like that the .css is "offline" and not in use in my theme, all changes have no result.
Did anybody has an additional idea for this problem???
