Playsms and Kannel integration Issue

Hi all,
I’m new to playsms and kannel. I’ve configured kannel successfully and have tested and its pushing the message. Now i’m planning to do the pull part and i’m using playsms. But when i try to click on the menu “Manage Gateway and SMSC” in playsms under Settings tab, I get a blank page.
Help needed urgently please

Is it the only menu that’s blank?
Can you show the log of your web server when you click on that menu?

Thanx for your reply but you want me to share my apache log or playsms log?
