Need help!

A month ago I had installed the Steady Plug In for my WordPress blog. So far my subscribers had no problem entering my blogposts. Yesterdays blogpost is a different story: I am getting complaints from some readers that the text stops in the middle of nowhere, long after the paywall. (others don’t seem to have that problem).
I have no idea what the problem might be. I would be more than happy if you could enlighten me!

Thanks.
