As per the current content, "Please Login first" message will be hidden from the users who belongs to registered token and rsfrom 123 will be visible to them.
Kindly share what you have configured in the plugin so that we can identify the issue.
If you are displaying content through RSForm Pro, then probably it won't work. Our plugin works on OnContentPrepare event, and seems that RS Form does not trigger this event before displaying content.
So it won't work with it.
