Yesterday I posted about the fact that I can't accept answers even though the last edit for answer was long ago. After cookie deletion, I managed to accept one.
When I click on tick to accept answer, I get message box saying that I can't accept answer in X minutes. After this X minutes the message box appears and text is the same. I am using regular view I believe.
Today the story repeated. Refreshing the page didn't help. After logging out and logging in again I could accept the answer.
I believe that this is bug. Please take a look at it.
