Issue with content not showing

I have tested the Schedule Selected Content Plugin for members content on my site, but have an issue with the content not showing up, when the timer runs out. The page just continues to load and show the short message from the plugin.
Do you have a fix for this issue?
My site is socialva.net, but the content is only shown to registered members.

This is the setup I have used. The content should show up for a week before being removed. Using WP time.
