I'm trying to add a Share button to my website's various pages but I've found so many options I don't know which one is the most correct.
Official method: https://developers.facebook.com/docs/plugins/share-button
I can't get this to work. If you'd like to check out a live example on my website pls comment :-) The share button appears, I click it, it opens but when I click 'share' again in the dialog, nothing happens. (the fb account is fine, I checked using other website's share buttons)
SO answer using share.php which I heard was no longer officialy supported: facebook Sharer popup window
Finally the facebook share dialog (official): https://developers.facebook.com/docs/sharing/reference/share-dialog
This method lists the use of 'app ID' which I'm having trouble with. It says to use a public ID and it IS required (not according to several SO questions), and I can't find how to do that.
Hence, I ask: What is one method that will surely work to implement normal share button (topic+image+small description) on my website? Thank you.
