Re: Retrieve the “secret” value
The “secret” in the installer is only relevant once the new cookie creation methods in WordPress trunk are ported across to bbPress.
That should be soon.
Matching it with the secret in WordPress is only necessary for integrated installs.
Furthermore, there are two secret values. One in the config file, and another in the database.
The only way to retrieve them from WordPress at this stage is to look at the config file and to manually query the database.
I realise this is messy at the moment and I am trying to get things up to parity with the current WordPress trunk.
