getting duplicate posts on activity list and duplicate email sent (new discussion, new comment notifications). Also, visits aren't being recorded and activity dates on profiles don't update.
We have two forums on the same server, one was installed in Nov 11 using v184.108.40.206 and we didn't encounter any of these issues. But installing the 2nd forum using v220.127.116.11 (Jan 12) these problems have arisen.
I've tried looking for issues by comparing 'class.activitymodel.php' in each version, but the file has been significantly rewritten in v18.104.22.168
Is this file the likely candidate for these problems occuring?
