* How to dupe the error. Please provide the specifics as to what you did to arrive at the error. Where within the site did the error appear? What is the specific error that you have received if you are getting one? I accessed the index.php to trigger an installation, and I'm getting this error message: No WPMU site defined on this host.
* Give details. Please remember that you're the one seeing the error and many times, you're the only one seeing that error. Folks can't read minds or else they would be in Vegas playing cards instead of trying to help other folks on the Mu forums. I followed the README.txt closely. The only step I didn't know to do was the Apache portion. I am running a WPMU site on another domain on the same hosting account, so I don't think I need to change any Apache settings. I did update my php.ini according to the README.txt. I do not have a wp-config.php file created. I deleted the .htaccess file.

Site is http://beerandblog.com/index.php. I have a placeholder up at http://beerandblog.com/ so make sure to use the index.php in the address

This is your problem. Wildcard DNS and Apache ServerAlias not set up properly.

Another suggestion: search the forum before posting. Really, entering 'No WPMU site defined on this host' into search box would have brought you valuable info to start from.

Dude, I thought my thorough completion of the information indicated I had looked through the forum and did not find an answer. I made sure to indicate I had read the README.txt, followed the directions, no wp-config (which is what most of the search results indicated for my error message), and that I had deleted the .htaccess file. I made sure to provide all of the details requested on http://codex.wordpress.org/Debugging_WPMU. So why the snark?

Can you help me understand why does WPMU work for one add on domain and not another when they're on the same hosting account? Wildcard DNS works for the other install.

Because you're on a shared host the new install is reading the config file of the other install. Thus, spewing the "no wpmu defined on this host" before you've even installed it.

rename the other config file for five minutes while you set up the new one. that's one fix.

Argh, i can't remember the other one.
