Thread:Extension talk:Maps/Maps not loaded but not active ?

I've installed Maps 3.2.3 through composer on a MW 1.23.9 setup

Issues :
 * #display_map is not parsed
 * Maps is not listed in Special:Version page, as well as Validator -> not loaded ?

Maps code is actually loaded (I've added an echo line into Maps.php to check it) and the contained user function is also executed (also tested with inserting echo in the function)

I've stripped down my LocalSettings.php to a minimum, especially disabling any other extension, thereby excluding interference from any other extension.

If I comment out the loading of Maps.php in vendor/composer/autoload_files.php and add a require_once(extensions/Maps/Maps.php) to my LocalSettings.php, Maps is visible in Special:Version and the parser function works fine.

as the extension registration code is executed, what can happen that causes the extension not being displayed on Special:Version. I assume that one I solve this issue the parser function may also work fine !
