I have been unable to vote in this sweeps for awhile now. I click vote now and it goes to a page with graphics but no submit vote or log in buttons. Anyone else having this problem? http://www.sweepstakestoday.com/sweeps/details/67425/kellogg-2018-celebrity-crunch-classic-sweepstakes
Looks like it turned out to be an "unsafe script" loading issue. There was a tiny warning icon up in my address bar for the site. I finally noticed it and clicked on it to go ahead and load the script and the page fully loaded for me.
