Legacy License Keys in QCLF: Display, Clear, and Migration Behavior

Explain read-only Legacy License Key compatibility, Clear Saved Key, updater credential cleanup, and immediate Authorized-Domain re-resolution without deleting forum data.

This guide follows the accepted QC Live Forum 1.1.27 implementation and applies to Upgraded installations; administrator. This category establishes the installation, entitlement, update, administrator, and permission foundation that every other QCLF workflow depends on. When older walkthrough or project-manual wording conflicts with 1.1.27 source or later accepted Authorized-Domain behavior, the current implementation takes precedence.

Before You Begin

• Take a current Joomla/site backup before installing, upgrading, changing component permissions, or making entitlement-related repairs.
• Confirm you can access Joomla Administrator, Extensions, and Scheduled Tasks.
• Record the installed QCLF version plus the current Base tier and Effective tier before changing licensing or task state.

Current QCLF Behavior

Step-by-Step Workflow

1. Open the relevant QCLF frontend or Administrator screen so the concepts in this guide can be compared with the current UI.
2. Identify the current Section, Category, Topic type, user role, Effective tier, and permission context.
3. Compare the current stored/state information with the behavior described below.
4. Use a safe test Topic or non-production forum area when you need to confirm a boundary rather than inferring it from the UI.
5. Return to Status or the relevant Browse/Moderation view to verify the final state.

Explain read-only Legacy License Key compatibility, Clear Saved Key, updater credential cleanup, and immediate Authorized-Domain re-resolution without deleting forum data is part of the current QCLF 1.1.27 behavior. Treat the current server-side state as authoritative: frontend controls are useful guidance, but QCLF still rechecks Joomla access, QCLF action permissions, feature state, entitlement, and the target object's current status when the action is submitted.

Operational behavior is preservation-first. Scheduled work should be repaired rather than bypassed, ordinary upgrades should install over the current package, and maintenance should not discard Topics, Messages, follows, moderation history, or other customer data merely because a runtime feature is temporarily unavailable.

How This Fits into QC Live Forum

This category establishes the installation, entitlement, update, administrator, and permission foundation that every other QCLF workflow depends on. A reliable configuration keeps Joomla authoritative for users, groups, access levels, sessions, mail transport, and Scheduled Tasks while QCLF owns forum structure, Topic/Message state, personalization, live-session state, moderation records, and feature-specific rules. Keeping those responsibilities separate makes troubleshooting much faster.

For Legacy License Keys in QCLF: Display, Clear, and Migration Behavior, verify the behavior with the role that will actually use it. Administrator, moderator, Host, signed-in member, guest, and viewer experiences intentionally differ. A successful test as Super User does not prove that a normal member or delegated moderator has the correct access.

Permissions, Entitlement, and Safety

• Joomla menu/view access, QCLF Section/Category access, QCLF action permissions, moderation scope, and commercial feature entitlement are separate checks.
• QCLF re-authorizes state-changing requests server-side; never treat a visible or hidden frontend control as the security boundary.
• Use Authorized Domains for current paid entitlement. Legacy License Key data is compatibility history and should not be reintroduced as the current activation workflow.
• Premium records and settings are preservation-first across downgrade; loss of current Effective tier can disable use without deleting the saved configuration.
• Do not expose passwords, saved keys, private managed-service credentials, or private guest identity data in public forum content, screenshots, or support posts.

Verify the Result

• The frontend Forum menu opens for the intended Joomla access level.
• Status reports the expected Base and Effective tiers and no structural entitlement warning.
• The five QCLF Scheduled Tasks exist; Entitlement Revalidation is canonical at 60 minutes.
• A non-Super-User test account sees only the forum areas and actions it should use.

Common Mistakes to Avoid

• Using old instructions that ask for a current license key instead of Authorized Domains.
• Assuming installation or opening the component starts the Max Preview.
• Treating backend component access as automatic frontend moderation authority.
• Uninstalling before an ordinary upgrade instead of installing the new outer package over the existing installation.

Troubleshooting

• Reproduce the exact action with the smallest safe test and note the user role, Section/Category, Topic type, and current state.
• If a control is missing, check access, QCLF permissions, feature inheritance, Topic state, and Effective tier in that order before assuming files are damaged.
• If a live or notification action is delayed, inspect the appropriate Scheduled Task and current lifecycle/delivery state instead of manually duplicating the work.
• If only one browser/device fails during live media, test browser permissions, autoplay/media policy, and network conditions before changing server configuration.
• After a correction, rerun the same test and reload the real frontend page; a saved Administrator form message alone is not end-to-end verification.

Operational Best Practice

Keep the forum model understandable: use the fewest permission and feature overrides needed, give moderators the narrowest useful scope, test live features with separate Host/viewer accounts, and keep Scheduled Tasks healthy. Before a major QCLF or Joomla update, maintain a current backup and a simple regression checklist covering Discussion, Search, Following, notifications, moderation, and every live Topic type you actively use.
