Magento admin extension fails to show in live server menu bar

I have recently built my first Magento extenstion.

It involves adding a new menu item in the admin area and works perfectly on my development server.

On the live server however, the menu bar item fails to display.

开发者_运维百科I am pretty sure that all the files have been copied over and I have refreshed all of the cache.

I have checked the system > configuration > advanced area and the module is listed in the disable section.

Are there any other settings/configurations I need to check?

Did you setup your menu with ACL roles? If so, does your user have the correct role?

Assuming the above is true, the Mage_Adminhtml_Block_Page_Menu class is responsible for rendering the menus. I'd start by adding some temporary debugging code to determine why this class is skipping your menu. (is it skipping it, or does it not know about it? If it doesn't know about it, why isn't your system reading it from the config) etc. etc.
