No Content Message on Cat after updating Membership 2

I have downgraded back to Membership 2 as it's a live membership program. Access has also been granted.

After updating Membership 2 pro, when accessing the protected cat we get the no content available message instead of the login page.

Reverting back to current version fixes the issue but means we need to run the older version of the plugin.

Your help is appreciated, let me know if you need anything on my end. I have backups and we are expecting this week to be slow due to U.S. Holiday Tomorrow.
