I think i have found what causes for the votes not to count after 1 vote is placed.
It’s because i’m using the PNG stars, when i used it, and someone voted already, it will only count 1 vote, after that no one can vote on that same voting star.
But if i use the regular GIF stars, the voting works perfectly.
The thing is, i don’t want to use GIF stars since it has white area on it, so is there any way to use PNG stars that works the voting stats just like GIF does?
