Problem/Bug Problem With Votifier

Votifier is giving me this error in console:

24.08 19:23:09 [Server] WARN Unable to decrypt vote record. Make sure that that your public key
24.08 19:23:09 [Server] WARN matches the one you gave the server list.

But I am using this votifier tester: https://minecraftservers.biz/votifier/test/, and it says it connects but it gives me that error anyway, I went back to my public.key folder and I put that one in there but still the same message occurs... help?
