I have looked at this so many times, I can see it any more. I have installed Cryptpad. Here is a snippet from
* CryptPad contains an administration panel. Its access is restricted to specific
* users using the following list.
* To give access to the admin panel to a user account, just add their public signing
* key, which can be found on the settings page for registered users.
* Entries should be strings separated by a comma.
So why doesn't this work?
