I was in the middle of a longish reply to this and went to do a preview and poof it all disappeared (dropped connection at my end I believe)
Anyway - I just went through this, successfully, only hiccup being getting TinyMCE working - the thread is here:
http://modxcms.com/forums/index.php/topic,64687.0.html
It was suggested that I could have done a re-install to fix, it sounds like that did not work for you.
Here is what I did
Do you have an active .htaccess file - if so it needs to edited (I turned off FURLs and deactivated my .htaccess - then pointed my new domain name to the site - then edited and reactivated .htaccess and FURLs)
There are several settings in the /core/config/config.inc.php file look for the ones which in your case will start with /notbadart and not the long ones
for example $modx_assets_url= ’/notbadart/assets/’; needs to changed to $modx_assets_url= ’/assets/’;
Clear the cache - it can be done manually by deleting the cache directory and its contents located in the core directory - it will recreate it when a page is accessed.
I believe that is all I did - you already have the base href in your template
Good Luck
