Leaky Paywall not working with new theme

Hi,

I changed my theme to “Responsive Blogger”. Didn’t change any settings on my Leaky Pawyall plug-in (and all the settings on the backend are intact). But, the paywall doesn’t seem to be working with the new themes. Pages that were behind the paywall (premium category) are now visible to non-subscribers. I have removed and re-uploaded the plugin but that hasn’t helped.

Please advice.
