I have successfully installed a membership manager script (Login Manager v3.0), which allows users to register on the website and gain access to online magazines for free. However, I have noticed that the pages that's supposed to be protected are still accessible just by entering the direct link of the pages on a internet browser.
It will be good if someone can help me troubleshoot this error. Many thanks in advance, as I'm a newbie in programming.
The link to the login page is... http://www.petsmagazine.com.sg/digitalmag/login.php
