title: Magento module works well on localhost but not on live server
body: <p>I have a weird case here....</p>
  
  <p>I'm making a simple magento module right now. Some kind of script injection module (similar to google analytics module). I've built the admin config for that module (which is defined from <code>system.xml</code>)
  <img src="https://i.stack.imgur.com/2hjPS.jpg" alt="enter image description here"></p>
  
  <p>as seen on the image. This module works very well on my localhost. But it's getting weird on the live server. The modules looks like it doesn't enabled at all although I have totally make sure it's all already enabled. Both via magento admin area and also via <code>app/etc/modules</code>. That admin config area never appear on live server's magento installation.</p>
  
  <p>does anybody know what's the issue with this problem?
  or at least tell me how and where should I debug it? I've been digging it to magento core code but getting stuck on getSingleton() function somewhere around magento core code. I don't understand that way-too-MVC stuff :p</p>
  
  <p>I would be very glad if someone could explain and guide me on this</p>
  
  <p>thanks :)</p>
