Pro Sites Plugin Checkout Page

Hi

We have upgraded to the latest version of WordPress and the latest version of Pro Sites.

On the checkout page, the custom text we have entered is displaying followed by the payment period, but the pricing options and option to pay or continue with a free blog is not displayed.

Choosing a payment period option doesn't do anything.

I have checked all of the settings and can't see anything obvious that is causing the issue.

I have attached a screenshot of what is displayed.

Please can you advise?

Many thanks for your help with this.

Emma
