License required
License gate page title (licenseRequired.title). The site will not run normally until a valid license is active.
Why this happens
No active license, verification failed, or grace ended. Status lines under the title explain revoked/expired/invalid/domain mismatch/unknown.
Diagnose and fix
1. Enter a valid key; activate/refresh.
2. Fix connectivity if verify fails.
3. See License key is required / License could not be verified.
4. See What the license key does.
