Thank you very much for this awesome share
I have same problem with this module and Ets Social Login , on 1.7.6 i think (if you have 1.7.6 we need latest versionhave try this module,
if you found error when install the module, repack the zip file without pdf file inside the folder.
in my case when trying google login, the information is success login but actually i'm not logged in to prestashop
is there anybody have success story with this module?
