Upgrading PrestaShop v.1.6.0.6 Problems

[DDavid]

Good day, i have upgraded PrestaShop to 1.6.0.6 version and now i have the following problems:

 

1) i can not see the newsletter module.
  Does not appear in the main page and does not appear in the live editor.

 

2) i have entered in the "block contact information" module data
  company but upon entering, in the main page in the footer you only see the title "Information about the shop"

 

3) the social module does not accept the link to FaceBook. It might be because the FaceBook page is temporary (it's just been open and we have less than 25 users) If yes, there is a way to insert it?

 

Thank you very much

 

P.S. The questions refer to the Italian version of PrestaShop. The names of the modules may not be exactly as written in the English version.
