On approving an edit, I just get this pop up since morning. At first I thought there might be some internet connection issue, but this is now the 3rd to 4th time I got the same error; also, the review is accepted because on refresh I can see my name with approved text beside, but it still throws this error.
I am on a Windows 7 machine, running Firefox 24 (Icognito/Private Mode)
Also, this happens only when
edit(1) is written on an question/answer, I don't go to review queue and approve, these reviews were directly loaded from the notification beneath the question/answer.
Martijn Pieters reproduced the problem from the review queue three times; each time the improve option was picked, accepting the suggested edit but editing the post some more. The network console shows that posting to
http://stackoverflow.com/review/task-reviewed fails, the server responds with a 404 error:
On the suggested edit page itself, no record is made of the accept; instead the suggested edit is recorded as approved by 3 people not including Martijn Pieters. In this case the improve review arrived too late.
In another suggested edit review, improve again resulted in the error, but the Community account is shown rejecting the edit.
