It seems that there is an issue with votes/reputation on Programmers.SE (don't know if there is the same issue on other SE websites).
I've recently answered two questions and my answer had one up-vote each, but the up-vote is not reflected in my profile. The reputation remains the same as before, and "votes" display is weird.
Here's a screenshot:
You can see that for non-wiki questions and my non-wiki answers, for both answers the reputation has +0 instead of +10.
The links to the answers are:
Update: it seems that the same problem affects another answer. With 34 upvotes, there are 215 reputation points (15 as accepted answer) instead of 355.
It makes me think about another point. At the beginning, I published this last answer as a community wiki (see edits history). But it didn't work, i.e. the answer was displayed as a non-wiki. Then, I edited the answer, without checking the wiki checkbox again. May it be that it affected every other answer, so now, every answer I write is treated as wiki, while being displayed as non-wiki?
