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?
Finally I got the answer. Increase the max_execution_time in php.ini file. It solves the issue.
