Carl,
What browser are you using? I just registered on the site and did exactly what you said (clicked Monthly Competition) and was taken directly to the right page (I see like 4 items I can vote for and the current counts). I also, then, tried logging out and back in again a few times, and each time hitting the Monthly Competition.
I did the initial registration and testing in Chrome. I then came back to the site in Firefox and logged in, and things worked normal then too. Both using Mac OS.
Can you try closing your browser to clear the cache and see if that improves things? Otherwise, try a different browser or computer. No clue why that would be happening, and obviously, it shouldn't. If it continues though, let us know and we can test more.. but any information about your computer/browser setup will help.
Finally, thanks for the compliments on JFBConnect. We always love to hear from our happy users... even when they're reporting an issue
