I implemented addthis on my company's blog based on Joomla CMS : http://www.escapar.com.co/blog
I observe a really weird behaviour with counters.
-or all my article counters are fine except for my article posted on june 24th.
-or none of my article counters work except the one from june 24th.
Anyway, counters never will work for all posts at the same moment.
I hope someone will be able to help,
