Problem/Scenario – On my website (http://dcjtech.info/) using the latest version of WordPress, BBPress, and BuddyPress, I closed a topic in my forum. Now, the tags belonging to the closed topic are listed as “empty topic tags”. This issue is always reproducible.
Specific Example – For instance, I closed a topic (http://dcjtech.info/topic/lindows/) and then I see under “Dashboard > Topic > Topic Tags” that “linspire” has a count of zero. Also, in the BBPress statistics widget, it says there are twenty “empty topic tags”. However, http://dcjtech.info/tag/linspire/ lists the Lindows topic as a topic with the “linspire” tag.
Question – Why do these “empty topic tags” appear/form when closing a topic and how can it be fixed and prevented?
