Draw.io blocking settings page

[noci2012]

The checkAdminUser call redirects the settings page to de default /apps/files page. Which is not desirable. (Nextcloud 17+ behaviour combined with groupadmin ).

Solution: Either disable the offending app or See here for the solution: https://github.com/nextcloud/server/issues/18865

in this case: apps/drawio/settings.php

+if (!OC_User::isAdminUser(OC_User::getUser())) {
+        return;
+}
-User::checkAdminUser();
