[Plugin: Tweet, Like, Google 1 and Share] translation disappeared

from a few days the facebook like button is not translated anymore in italian as it was before.

I’ve checked the plugin options page and it still lists “italian” as selected language, tried to save the options again but no way, it appears in english.

sudiptomahato, can you check the code?
