Plugin not showing up completely

Hello,
First, thanks for your plugin. It is very good but i have a problem.
The first days the plugin works perfectly and since today the plugin is not showing completely.
Here is an example : http://www.servicegagnant.net/2012/10/24/el-mosquito-ne-piquera-plus/

How can I fix this issue ?
Thanks for your answer
Cordially
