Okay, I installed Modx (1.0.4) on a server on a home computer. I don’t know how to fix this still with Dreamhost as my provider, but just in case anyone else comes across this problem — when everything works, the configuration panel and tabs DO NOT APPEAR AGAIN, that is, after a clean, problem-free installation, the panel totally disappears. If you need to alter the configuration post-save, it’s not in the database, but in a file in your Modx folder: /manager/includes/config.inc.php. Go in there and make alterations as needed with your ftp program (at least that’s one of the primary places).
I kept thinking that the panel would still exist to make alterations after I pushed the save button, but I guess not.
So, also, when you open the admin section directly after installation, go through that config. panel as THOROUGHLY as you can, because after that, it looks like those settings are only alterable in the files themselves.
