I have no idea why that would happen tbh, you seem to have all the necessary permissions, no bans or anything like that (as far as I can tell). I'll see with another donator (when there's one around) if it's related to the rank, which it shouldn't. If you have any idea why that could happen (is there a reason why admins could've blocked you from using polls?), tell me and I'll take a closer look, but as far as I can tell, everything should be set up right.
