Optimal different look on different browsers

Wes,

I have loved your work for a long time and purchased many themes. I used Optimal for a client a couple of years ago and usually use Chrome to see the website. This morning I used Firefox and the site was completely different, then I looked on Safari and it was also not the same site I was used to seeing on Chrome.

Did I do something wrong, did the theme change or something else I missed. I thought for sure the site was fine, so I am not sure WHEN the site changed or how I missed it. Can you please take a look?

Thanks.
