And as it is I don't know if he has received it or not. And I think I experienced this yesterday too but I forgot to mention in the thread I created. I think there are some bugs to fixed in the karma log.
Based on the
karma log, hugeblack did receieve +1 7 minutes before your posts, so it's safe to assume that they received the +karma.
The most obvious reason why this happens is due to the forum auto-refreshing the request. For example if the page is slow to load, by trying to load again then the error will occur even though the +karma is already sent. Either that or as someone else explained double clicking causes this. Given the karma is still sending ok, it's not much of an issue tbh even if inconvenient.
In the past when receiving these errors I've always taken it as confirmation that my karma has been sent, or otherwise that I am trying to re-give karma to someone with 10 hours, rather than assuming there is an issue with karma issuance.
I think this problem is due to admin trying to deploy that resource of Karma showing per post
As far as
admin has said, he has not attempted to implement this onto the forum yet, so is unlikely to be the cause.
