Hi I have a question regarding the upvote/downvote buttons, they are currently set to + and - and I can't find a way of changing that - ideally I'd want them to say "helpful" and "unhelpful" instead. Tried changing it with css by changing the wpd-vote-up wpd_not_clicked to hidden and using the :after thing but it doesn't seem to be working (it hides it, can't change it).
thanks for help in advance,
