TearSnow Update Lock Cleaner is a lightweight utility plugin developed by TearSnow in collaboration with Fanly to resolve WordPress update lock issues.
It automatically removes core_updater.lock, auto_updater.lock, and related update transient data, restoring the normal WordPress update process. After execution, the plugin automatically exits without providing any admin UI, database changes, or frontend impact. It is designed for emergency recovery scenarios.
During WordPress updates, the system creates a temporary update lock in the database to prevent concurrent update operations and data corruption. This lock is typically a timestamp value.

✅ Under normal conditions: the lock is automatically removed after the update completes or expires within approximately 15 minutes.
❌ If an update fails or is interrupted: the lock may remain permanently, preventing further updates unless it is manually removed from the database.

When WordPress detects an active update lock, it blocks further updates and displays the message: “Another update is currently in progress.”

How It Works
WordPress creates update locks during update operations to prevent conflicts. These locks are normally released automatically after completion, but may remain in the database if an update fails or is interrupted.
TearSnow Update Lock Cleaner detects and removes the following items:

core_updater.lock
auto_updater.lock
update_core transient cache

After cleanup, WordPress update functionality is restored to normal.
