Magento

Hi, does anyone have experience with magento custom module in v1.4?  I have the SEO module Yoast Filter (http://yoast.com/landing-pages-module-magento/) working great in Magento 1.3, but when I moved to a new server with a fresh v1.4 install, I can’t get the module to install again - it won’t even show up in the admin page (system -> configuration -> advanced ).  Their bundled module, Phonenix_MoneyBrooker was the only 3rd party module showing up on the admin advanced configuration page.

Did magento changed the way the plugin is installed?  I saw some suggested to add an admin.xml file to the /etc folder, but the Yoast Filter is a front end module and I’m not sure if that’s relevant.

Thank you for your time in advance!
