I have tried to update my GP Premium plugin but I have got this message: An error occurred while updating GP Premium: Download failed. Unauthorized
What can I do to solve this? Maybe it is because I activated the plugin in a localhost WordPress and now I am trying to update it in the real online site: http://vanlauwer.nunezcommunications.com
If your license key is already activated, but you’re getting an “Unauthorized” message, you most likely need to remove your license key and save – then re-add it and save.
This happens when your URL has changed since your license key was activated.
