Why paid member still can't see protected content?

I’ve done:

1. User (test01) is an active paid member.

2. User has been granted “Sliver membership”

3. Silver Membership including [level-twittes].

4. /real-time-news/ has content like this:

[level-twittes]Here is the Twittes[/level-twittes]

[level-premium-content]Here is the sample of Premium content[/level-premium-content]

Situation:

Pages contain shortcodes been redirected to “/protected/” after login, even home page.

Please advice.
