Issue: Cannot vote in open polls

Even though this is not a big problem, I thought I should report it. I've been away from the forum for several months, and the last time I was here, around September, I was able to vote on every poll normally. Now, I've realized that every poll in the forum is closed to me, no matter what sections they are in. They all show me the results and say "You may not vote on this poll". I have tried to see if it was my account for some reason, but I couldn't find anything out of the ordinary. If I try in different browsers (latest Chrome and Firefox) it's still the same. I've also tried changing the theme to see if it would help, but it doesn't.

I hope this bug can be fixed, but if it can't it wouldn't be too much of an issue.
