I installed EmailAuthorization 1.3 (6c290e3) on MW 1.30.0 (5.6.38-0+deb8u1) with PluggableAuth 5.2 (2528a75), and ran update.php.
Now, even though I have the proper permission and can see Special:EmailAuthorizationApprove, I "get page doesn't exist", upon requesting Special:ConfigEmailAuthorization
