December 15, 2014 - JFBConnect v6.2.4 released (changelog). Includes channel setup improvements and numerous bug fixes.
Before I use JFB, I used other Facebook's comment/like plugin called "KA Facebook Comments" and got few comments and likes on pages.
Now after replacing the system to JFB all the comments and likes disappeared.
Is there a way to show the old comments/likes?
Unfortunately, there's not a real good solution for this. From our understanding, KA Facebook Comments uses the older method that Facebook allows to identify each page on your site. In early March, Facebook updated it's comments box to use a URL to identify each set of comments. We had a method for JFBConnect users to keep old comments intact during the transition, but the previous method to identify each comment box was by creating a unique ID for each block of comments (123, abc, etc). KA Facebook Comments and JFBConnect generated this ID differently, so there's no way to migrate these comments from their system to ours.
Hope that helps explain, and hope it's not too inconvenient for you.
Unfortunately this is a bad news for me. I cannot change the system.
Also I found know that the notification for admin is not point to the article that commented.
Keep up the good work.
