Derek – Could you elaborate on this?
“The fourth gotcha! was when I edited the .htaccess file with the path to wp-inst Donncha’s new RewriteRule. I inserted the full filesystem path but this generated multiple errors. I found that only the directory portion leading to my WPMU root was necessary, in my case /subdirectory/wpmu/ was necessary instead of /fullfilesystempath/sudirectory/wpmu.”

What/which line did edit in htaccess.dist file? What’s “wp-inst Donncha’s new RewriteRule”? I am having that crazy mysql error during installation..

Thanks alot!
