I still get the same message that says can only vote once a day and to come back tomorrow - and I know it was earlier than this when I voted yesterday.
And I just tried again and got a security certificate warning, so I tried with Firefox and got the message:
This Connection is Untrusted
You have asked Firefox to connect
securely to
www.facebook.com, but we can't confirm that your connection is secure.
Normally, when you try to connect securely,
sites will present trusted identification to prove that you are
going to the right place. However, this site's identity can't be verified.
What Should I Do?
If you usually connect to this site without problems, this error could mean that someone is trying to impersonate the site, and you shouldn't continue.
(I clicked on the link from the first message in this thread and wasn't trying to go to Facebook itself)
