Site not behaving when I drop sub.domain

Ok, I’m a bit stumped here. One of my domains is alpha-byte.ca and the folder on the server was [tt]/www/folder1[/tt]. I made a subdomain m.alpha-byte.ca and installed modx 2.1.3-adv into [tt]/www/modxabc[/tt]. I’ve now changed the pointer for alpha-byte.ca to [tt]/www/modxabc[/tt]. So as it stands, alpha... and m.alpha... point to the same folder, and the manager pages work perfectly.

The problem is this:
http://m.alpha-byte.ca/webdesign/ works but
http://alpha-byte.ca/webdesign/ (or any other resource pages) gives me just my landing page.

http://alpha-byte.ca/phpinfo.php will give you the server details.

Thanks in advance for your help.

PS: I could have sworn there was a System Setting that defined the proper [tt]site_url[/tt] value but I can’t find it.

It’s in core/config/config.inc.php. It normally gets set when you run setup.

Try running Setup in upgrade mode if you haven’t already.

I’ve tried putting the /core and /setup folders back, and run the update from the proper, non-sub’d domain name and still only m.alpha-byte.ca.

Any other ideas out there?

What I've resorted to most recently is:
1 - copy/pasting templates and resources into a plain text file
2 - dropping all tables in my mysql database
3 - wiping out all files in the directory
4 - doing a from-scratch install of modx 2.1.3 adv
5 - avoided installing packages
6 - activated Friendly URLs in the System Settings grid
7 - pointed the Site Start Document to #2
8 - made certain that .htaccess file matched .htaccess file for another modx site installed along side this one which does work
9 - made three documents, each with links to the others
10- double-checked that the links generated were formated properly: http://alpha-byte.ca/home.html for example
11- and almost cried when, after starting on document 2 as expected, document 1's content comes up for all other links.

I have http://diebot.org/ which does FURL's flawlessly and http://alpha-byte.ca/ which only works with index.php?id=n even though FURL's are on.

Thoughts? Questions?
