I have been trying to remove the Up vote - Down vote buttons from Answers.
I have successfully turned this Off under the Viewing options - However it also Removes the Tick Button to Select an Answer.
I have done some tests & it seems to be caused by the SnowFlat theme.
I've tried to fix it myself with no success, however i have modified SnowFlat & built my own called DarkFlat. - Still can't get the Tick Button back.
