HMVC, i18n and Simple Templating System, but Redux Auth Library Problem

[eluser]outrage[/eluser]
Just a quick guess without looking... are you using any MY_ prefixed resources?

The documentation for HMVC says:

Do not use the MY_Controller extension in your application/libraries directory. This will cause CodeIgniter to bypass loading Modular Extensions and modules will not function. If you need to run methods in a base controller define them in another module controller and use the controller autoload functionality.
MY_ prefixed resources are not loaded by ME when they are inside the module directory (e.g., MY_directory_helper.php is not loaded when it is in the modulename/helpers directory). This is because ME doesn’t check for MY_ extensions in modules. To get new functionality using helpers, plugins, models, etc… either make a new named file and load that resource or put your MY_ prefixed resource up in the requisite application directory (helpers for a MY_ helper, libraries for a MY_ library, etc…).
