Protection, and Redirection issue

There are two issues:

1) The post isn't showing fully for the users signed up for respective membership. The content remains protected. However, it works fine with another test user having same membership.

2) Once the member registers via /register link, they aren't getting redirected to Thank you page. This should be the default workflow, but not working at the moment. It's getting redirected to /membership page at the moment.
