Configure Joomla Group Permissions for a QCLF Section
QCLF Section ACL is intentionally narrow: the current Section permission matrix controls one action, View Section. Detailed create/reply/moderation permissions live at the Category level.
Use Section ACL only when Joomla Access Levels alone are not enough to express who should see a Section.
Open the Section Permission Matrix
- Open Components > QC Live Forum > Sections & Categories.
- Edit the Section.
- Open the Joomla group you need under Joomla Group Permissions.
- Set View Section to Inherit, Allow, or Deny.
- Save the Section and test with a user in that Joomla group.
What Each Choice Means
| Decision | Meaning |
|---|---|
| Inherit | No explicit Section ACL row is stored for that group/action. Other visibility gates and any applicable inherited-group rule decide. |
| Allow | Stores an explicit allow for View Section at that group. |
| Deny | Stores an explicit deny for View Section at that group. |
Section Visibility Still Has Other Gates
Even an ACL Allow does not bypass structure entitlement, publication, or the Joomla Access Level. QCLF first checks those conditions, then resolves the custom Section ACL rule.
When no applicable explicit Section rule resolves to Deny, View Section remains allowed after the earlier gates pass.
Joomla Group Inheritance Is Specificity-Aware
QCLF evaluates the current user’s authorized Joomla groups, including inherited ancestors, but begins from the leaf-most direct assignments so a specific child-group rule can override an inherited parent rule. At equal specificity, Deny is the safe tie-breaker.
For example, a Support-group Allow can override a Public-group Deny inherited through the Joomla group tree.
Test the Real Group Combination
- Test a user assigned to the actual child group, not only a Super User.
- If the user is directly mapped to both a child and one of its ancestors, QCLF still treats the leaf-most direct group as the specificity root.
- Remember that hiding a Section also hides its Categories because Category visibility requires the parent Section to be viewable.
