Problem: Access Level and Super User Logins - Joomla! Forum - community, help and support

-

i posted before saw there forum specific acl:

viewtopic.php?f=624&t=774683

the problem posted: member of super added other user groups. user no longer able login backend despite belonging super.

i suspect in 1 of groups person added permission admin login explicitly set denied. setting cause behavior. problem of explicit denied setting - adding user multiple groups permissions can lost , not intuitive why happens. better practice never (at least "almost never") set permission denied, rather leave permission inherited (which implicitly means denied unless somewhere else user belongs group set allow).
