I'm so sorry I left that information out. I'm using Joomla 1.5.23, but I must confess that I can't seem to find a version number on the KA FSC - perhaps I am overlooking it? I can say that I only purchased the plugin a couple weeks ago so it must be a recent version (I did open kafacebookcomments.php but there was no version number listed that I saw.) If I am looking in the wrong place, please let me know and I will provide that information straight away.
I followed the instructions for creating Facebook applications (one for Comments and one for Like and Share) and as a result I have two Facebook App IDs... I put in the same website url for each app, so shouldn't Facebook have left the App ID the same?
As a question on the side: it seems Facebook allows developers to create Apps very easily, but what's the point if you can only have one on your website at a time? Do I actually need a second Facebook App for the second plugin?
Thank you for helping me with this, I apologize for being such a pain.
You are correct! It seems to work now... thank you very much for all of your help.
May I recommend adding a notation of this information in the guide to setting up a Facebook application? Seeing something to the effect of "keep in mind: you only need one Facebook app no matter how many KA plugins you wish to install" might be helpful for others like me who are very new to this.
Just an idea. Thank you again for all of your help with this.
