Facebook like button missing after update

Hi,

After updating a site based on myFolio template to Joomla 2.5 (joomla package + myFolio template),
my facebook like button disappears.

I made the update of the template by replacing all the files via FTP.

The button code is of course still present in my social module.

What could be the source of the problem ?

PS : I have a copy of the site with Joomla 2.5 but myFolio template for Joomla 1.7, and there is no problem the button is here...

The solution was so evident, that's why I didn't see it immediately...

By erasing all the templates files, the facebook script included on default.php file (for generate the button ) was erased too...

If it can help someone
