I am getting the same error message:
Warning: $project isn't set in /home/content/s/i/m/simplewebsites/html/sapphire/core/ManifestBuilder.php on line 154
Fatal error: DB::connect: Not passed a valid database config in /home/content/s/i/m/simplewebsites/html/sapphire/core/model/DB.php on line 53
I also had no config file. I used the code you placed on an earlier post to create a _config.php file adding database name/username/password and I still get the error messages. Can you please assist?
