I have had no problem with Facebook's App's working with out a SSL Certificate.
With the Facebook 'Approved' items; Email, Public_Profile, & User_Friends SSL isn't a requirement. The other integrations requiring approval that need to be reviewed by Facebook before they can be used can need an SSL.
Again I haven't had any problems before.
Can you please make absolutely sure before I purchase an SSL Certificate that, I do indeed need one?
Again, there is no requirement to have an SSL Certificate needed for the Share4 Points before purchasing.
If it IS a requirement after you have tested SSL/NONE then you should add that to your product description.
So let me know when you have tested the component/extension on a domain WithOut SSL.
Cause it needs to be listed as a requirement, if it is one. (it's almost JED Review time!)
Thank you
