This will be fixed when @RastaLulz is online, until then you should probably disable the voting on your retro, if this isn't your retro, try to use some parameters in the URL such as "?novote" or "/novote" can't assure you that they will work, but the hotel will have at-least one way of accessing it.
Thank you for the report. Voting has been disabled for now. This means that everyone will be redirected to where they're suppose to go, and will not be asked to vote again until the next voting cycle.
