I can get the 3 subscription buttons to appear on a page on my Google Blogger.com site, however when I click any of the 3 buttons, the popup window appears, shows a spinner, and then closes without letting the user sign up for the subscription.
I've checked that popup blockers are off. (and the popup window appears, shows a spinner, and then closes).
I've tried adding the <script> to the theme <head> and also in a layout HTML/Javascript widget.
Is this possible to do with Blogger? If so, how can I get this to work?
Thank you.
