I wrote a message about this a few weeks ago, but did not receive a reply from JP's authors.
After the latest upgrades, my Facebook 'likes' went down on my site's home page. Before, the likes was pretty much keeping up with the likes on our Facebook page.
I assume that 'official buttons' means JP is taking the count from our Facebook page - that's what the help page for sharing says.
I assume the home page is linked to the FB page. I don't know about my website's other pages; it seems they should be independent.
Why did our likes go down in count (from 74 to 52)? It is now at 55. Our FB page is 99 likes.
I'm using official buttons.
Frankly, it's not a huge issue or problem, but it's worthy of a 'Why the heck is this happening?"
