A module is missing from the admin

Check that the module is an Erlang application in a discovered project directory. Confirm the application name, .app.src, main mod_... module, and successful compilation.

Then refresh discovery using the normal update workflow. Look for a compilation or dependency error in the logs. A directory containing templates alone is not necessarily a discoverable module application.

Once the module appears, activate it for the intended site and check its state. Discovery and activation are separate steps.
