Problems applying a theme

I am trying to apply a theme that I have used in the past. After saving the theme and going back to the form builder, the theme does not change.

Inside of this guide you can find out how to use your JotForm Themes:

http://www.jotform.com/help/184-How-to-Use-Your-JotForm-Themes 

I have cloned your form https://www.jotform.com/form/52145116790957  and successfully applied one of my themes. Here is my cloned form: http://form.jotformpro.com/form/52145421654955?

I would suggest you to clear your form cache and browser cache. 

You can also try using different browser. 

Hope this will help. Let us know if you need further assistance.
