PS 1.5.4 - Problem with module "Social sharing"

[Vitter]

Hello everyone!
I tried to install the "Social sharing" module in my shop to give a chance to the social sharing.
Once the module is installed, when I try to click on a product in my store, the page becomes white and I read the following message:

"The www.............. page does not work.
www ....... is currently unable to handle the request.
HTTP ERROR 500 "

 

Everything returns to normal when I uninstall the module.

 

Can somebody help me? 

(Sorry for my bad English).
