The topic component under Q&A in communities shows # of posts as 0 under user avatar. Seems like the back-end or front-end is not getting the count correctly. See attached screen shot.
Since this is pre-build component I am raising question in the forum rather then digging deep to see whats going on. Did anyone face this issue before?
The below user has posted multiple topics on the site. (Developement version)
It's an artifact of an old code, which was not removed untill recently(Removed in 6.4). The backend attribute for this count is not evaluated and it was removed after it was deemed redundant by product management. You can get the same info(infact more detailed info) by visiting profile of a user and looking at it's activities tab.
You can overlay the post and remove it from UI without any side-effects, if you are not planning to upgrade to 6.4 in near future.
