Glitch found in Pay Per View Plugin–Allows readers to access content free

Hello. A reader of mine has found a glitch in my Pay Per View paywall that allows viewers to access all of my content for free (and presumably anyone else’s content who is running this software). The glitch is that the paywall does not kick in when viewers access the content through a tag or date extension.

I thought this might be because I had my settings allow for search bots to see the full content, but I then switched this off and was still able to access the content for free (and yes, I did have my admin access limited to not seeing the full content). Below are a couple of examples of extensions where the content can be accessed for free (first a tag extension, and then a date extension).

This is really not good. Please respond ASAP. Thank you.
