Answer 1

I have the latest Magento 1.9.x.x installed and had a similar problem. To debug it this question helps me a lot:Why is my Magento module not being loaded?. Basically you need to check Mage_Core_Model_Config. I also wonder why I can see my module in System->Configuration->Advanced->Advanced but it gives 404 error. Basically it's an error in Magento and the names for modules are broken. Somewhere Magento forces the names to have the first character Upper-case. It's not working with the first character lower-case (but it is shown in ystem->Configuration->Advanced->Advanced).
