User log in issue!

Here is some issue I have on my website: http://www.evergopackaging.com

The plugins I use are: Absolute Privacy, Facebook Like Box, Role Scoper, Visual Form Builder, W3 Total Cache.

I use Absolute Privacy plugin to create user log in only can see which page I want they to see, which work well in beginning. after 2 months, the issue start:

1. Sometime the website only show mobile version in the computer.

2. After User log in if not click remember password box got kick out automatic, if not open new window for next page got kick out too. which can’t see the page only for members.
