“Update failed. Download failed. Unauthorized.” Error When Updating
This error can happen when the license either hasn’t been activated for the current site or, the license was previously activated for the site but on a different domain (such as a staging or development domain). To resolve, go to Settings > Wicked Folders, enter your license key, and click Activate. If you’ve previously activated the license, click Deactivate first and then re-enter the license, and click Activate.
