Re: Errors in bbPress – seen on the Official forums
I still don’t believe there is any truth to the existence of a cache. Does anyone have proof of this?
I believe deleting either users or posts or topics, by whatever process, does not properly reset the last poster, number of voices, number of posts, number of replies, etc. Which is why I think this is related to either bugs or not fully developed or poorly performing plugins.
The functions exist, as ashfame explained, to fix problems. It should not happen on a regular basis.
From the “recount” page of the 1.1-alpha admin:
To minimize database queries, bbPress keeps it’s own count of various items like posts in each topic and topics in each forum.
If the plugin or even built-in functionality does not accurately update the count, then you need these recount functions. If the code were perfect (core and plugins) then these functions would need never be used.
