Hello

it is how joomla inheritage works
if you have set a deny in a parent usergroup
- then you can not use "allow" in a child usergroup

the solution is  at component permissions

1. check parent usergroups of the tree
2. find the "deny" and set them to "inherit"

Then at global config do the same
-- set to "inherit" or if you are the top-most level of global config set to "Not set"
