Sorry for the lack of details.
SMF 2.0.8(2.0.9 update)
Downloads System Pro: 4.1.5
I have also tested this on a fresh install of SMF 2.0.11
So global permissions work, they are currently set for regular members to be able to download but not create a download:
In the category submissions I click on "Category Permission"
I then set a permission to allow Regular Members to add a download:
I then see the added permission on the Submissions category:
I have tried allowing global permission and deny permissions on categories and none seem to work.
I took a look real quick in my Sources/ManagePermissions.php in case any "lite" information was there but I could not tell.
Thank you,
Didier
