The mailchimp signup in question is the one in the main revolution slider when you visit the page. It will say “out of stock” and prompt you to sign up for stock updates.
Feel free to enter a bogus email just to see the subscription message. Once the message pops up, it comes out a little crooked.
OK then what I did previously must have fixed it. I just didn’t clear the cache. Thanks!
In case anyone else runs into this problem, I clicked on the slider element I had added in cornerstone, then clicked the column section that the slider was under and clicked the center tool.
