title: Cannot access configuration page in drupal 7 site
body: <p>I am currently building a website using drupal 7.x. Unfortunately I cannot seem to enter the admin/config page. Every time I click on the configuration tab on the administration menu, I only get a blank page. Then I created another sample site. It also has the same problem and I am using WAMP server. I cleared cache and finds no difference. I have searched for similar issues, but could find none. Can someone please tell me what I am doing wrong?</p>
