If you used a temporary domain, you'll want to modify the config files that were set at install. If you didn't check the documentation for moving your site, but only that thread, there may be more config files you missed.
About halfway down in the documentation here :
http://rtfm.modx.com/display/revolution20/Moving+Your+Site+to+a+New+Server
are ALL the files you need to check into. You may still need to modify the variables in config.inc.php as is noted (before, your site was in a subdirectory, now you need to set the variables to '/' indicating a root install), and also these files:
/config.core.php
/connectors/config.core.php
/manager/config.core.php
Check the workspaces table as well, and delete the files located in the core/cache folder rather than using the manager to clear the cache.
Also, it's never a bad idea to re-run setup and in this situation, probably essential. I typically don't just use the setup folder, but rather I run it like an upgrade and merge all the installation files on the server. Follow the upgrading information here
