Problems with setting permissions of a mod

[sz1]

Hello Community!

I have a distinct problem with the Mod DownloadsII. Before someone points me to the page of the Mod: The problem has been addressed several times in the comments and never been answered.


As I imagined

The mod has a feature to allow or prohibit specific usergroups to access selected categories of the download area (see picture). The primary user group is for all users "Registered Users" (ID 2). But when they register, users are classified further into at least one (but no more than two) additional user groups.
The group "Registered Users" has a very limited access in the DL-area. The appropriately chosen additional user groups should extend these privileges.


What the problem is

Apart of the following the mod works fine. However, the permissions are not expanded by the additional user groups. Instead, only the permissions of the primary user group (registered users) are applied. If the primary group is allowed to see category 1 and the secondary group category 2, then users who are members of both groups only see category 1.

I don?t want to avoid the problem by juggling with primary and secondary groups. The arrangement should remain as it is. However additional groups should simply expand the permissions of the primary group. A setting error is also excluded - I've checked it all several times.

I don?t know where the problem is, so I just show you the code.

CLASS_DOWNLOADSII.php

PHP Code:

[...]

    {
        global $permissions, $vbulletin;

        // check for category permissions

            if ($permissions['downloads2extrapermissions'] & $vbulletin->bf_ugp['downloads2extrapermissions']['excludecats'])
            if ($permissions['downloads2permissions'] & $vbulletin->bf_ugp['downloads2permissions']['canaccessdownloads2'] = true)
            {

BITFIELD_DOWNLOADSII.xml

I really hope someone can help me. It's pretty important for me that I can split the visibility and the access rights for categories of the download area.
