Uninstall

1. Navigate to AdminCP > Add-ons and click Uninstall next to [MC] Sunset.
2. Confirm the uninstall when prompted.

The uninstall steps drop the five xf_mc_sun_* tables (user_state, snapshot, released_username, audit_log, reactivation_request), drop the mcsun_warning_optout column from xf_user_option, remove both cron entries, and delete the options, phrases, templates, template modifications, and admin navigation entries.

What is not removed

• The add-on directory at src/addons/MC/Sunset/. Delete it from disk after uninstall if you want it gone.
• Member tier state already applied to xf_user (anonymised profile fields, released usernames). Those mutations went through the policy assignments during the lifetime of the add-on and are not reversed by uninstall. Run mc-sunset:reactivate on any members you want restored before uninstalling, while the snapshots are still in place.
• xf_user_option.mcsun_warning_optout values. The column is dropped, so the per-member opt-out preference is lost.

Before you uninstall

Snapshots are the only copy of original profile values for members who were anonymised by a soft, hard, or released transition. Once the xf_mc_sun_snapshot table is dropped, those originals are gone. Either:

• Reactivate everyone you intend to restore first (mc-sunset:reactivate <user_id> or the per-user Reactivate button on AdminCP > Users > Sunset > User state), or
• Export the snapshot table from the database first if you want to keep the originals available outside the add-on.

The released-username table is also dropped on uninstall, which removes the re-registration lockout for any usernames the add-on previously released.
