I encounter some issues after update membership 2 pro

Hi dear support team;

I tried to update the membership 2 pro but I see some issues after upgrade. There are a few problems in the current version:

1- If a visitor goes to author pages, s/he can read the protected posts.

2- The protected page is visible for everyone. (Please check https://staging5.rice-exchange.com/rice-importers-database/).

3- If I update the plugin, the posts are not visible. It says “No result founds, …”

This is a staging copy and the plugin is not updated yet. Please feel free to work on this staging copy.
