Re: I can’t install bbPress.
OK – everything appears to be in the correct location now. I think there is just a simple problem with the config.php database details now. Can you verify that these 4 are absolutely accurate in your config.php?
The host might not be localhost. Mine is not. And you don’t have a syntax error in the file (like a missing or extra quote) but something like one of those values is inaccurate. Posting it here in edited form won’t help, you have to verify that the database name, user, password and host are all accurate. You’re the only one who can do that. Once you have that, we need to get back to the original problem.
