My stackexchange.com profile, accounts tab shows no questions and answers on Programmers:

Programmers account, 141 reputation, 0 questions, 0 answers

My Programmers profile disagrees with that answer count:

1 answer with 4 up votes, 141 reputation

What's special about this answer is that I didn't have an account on the site when the post was migrated to Programmers.SE. My two answers on Server Fault are counted correctly, but they were migrated after I already had an account there.

Another example: This user on Server Fault only registered after his question was migrated from SU, and his SE profile shows 0 questions on SF.

Posting a question on Programmers.SE didn't fix the wrong answer count on StackExchange.com.


I deleted the question and posted an answer, which fixed the answer count, increasing it from 0 to 2:


After deleting the additional answer, the answer count was correctly reduced from 2 to 1.


So posting another post of the same kind will fix the issue for a specific user on a specific site. The bug still exists though, and probably affects hundreds or thousands of users.

My thanks to Yannis Rizos ♦, Programmers moderator, for allowing me to mess with his site!

    The Stack Exchange data is heavily cached and refreshed only when there are "reputation events", as the developers call them. If you will post new question or new answer, or even cast a vote the cache will probably be refreshed. Commented Sep 2, 2012 at 12:49
  • @ShaWizDowArd The problem is not that the data is out of date, but that it never was correct in the first place, possibly because of an (implied) assumption that accounts always have 0 posts when registered. Commented Sep 2, 2012 at 12:50
  • Indeed, the bug exists - not doubting that - just explaining how to make the list refresh and show the real data. :) Commented Sep 2, 2012 at 12:52
  • @ShaWizDowArd Makes sense. I just wanted to prevent further responses like "It's just out of date because it's cached" by clarifying that that isn't the problem here. Also, I up voted the other user's question, now the SE profile shows 6 rep, 0 Q, 0 A for SF; so rep caching is unrelated. And I don't want to post to Programmers.SE just to test other cache invalidation :-) Commented Sep 2, 2012 at 12:56
  • @DanielBeck Well, if it's for science I'll allow it (just flag after you post so I can delete...)

  • @YannisRizos Thanks. Deleted after a minute: programmers.stackexchange.com/questions/163376/… -- Did increase question count on SE, but didn't affect answer count. Now on to posting an answer... Commented Sep 2, 2012 at 13:40
  • @YannisRizos Answer posted and deleted here: programmers.stackexchange.com/questions/159789/… Commented Sep 2, 2012 at 13:48
  • ..and finally it's there. Actually it's not really cache, it's simply a different database as far as I know, synchronized through certain events only. Commented Sep 3, 2012 at 20:51
