Ubuntu 18.04.6 LTS
Ghost-CLI version: 1.13.1
I had installed Ghost a few years ago being used as a private blog. I had locked the website with the RSS lock. When trying to log back in, no access from the RSS and user not found from https://example.com/ghost admin signing. The Passwords are saved on a password manager there is now way they have been mixed up or changed.
What could be the issue here. How do retrieve the user credentials
Everything about your environment is old enough, perhaps you should consider just starting over. Login using SSH and use
ghost export my-export.zip to export your content.
Then start over with current versions of Ubuntu, Ghost and Node and import your old content.
I believe the credentials you are looking for are hashed (encrypted) in the database and you can’t simply retrieve them. I expect there’s some way to reset the credentials using SSH access, but given that everything is due for an upgrade anyway, I think starting over with an export/import of your old content may be faster.
