I suspect it's because my hosting company hates me. I'm attempting to get my eleventh (!) testbed up and running and I simply cannot get my multisite installation up and running. I've done this TEN TIMES PREVIOUSLY with the same host, each time with various issues but I've gotten it done regardless.
Attempt #1, preferred method:
* Created directory sites/domain.com.subdir
* Copied default.settings.php to directory sites/domain.com.subdir
* Duplicated default.settings.php and renamed the duplicate settings.php. Both files are in the directory
* Set directory permission to 755
* Set file permissions, variably, to 644, 666 and 777
* Created a symlink called subdir pointed at sites/domain.com.subdir
When I browse to www.domain.com/subdir I get the usual "Choose your language" screen. I choose English, the page sits there about two minutes, and then I get a "Page Not Found". Doesn't matter what permission I've set on settings.php -- same result every time.
Attempt #2, acceptable method and I'll take anything that works:
* Created directory sites/subd.domain.com
* Copied default.settings.php to directory sites/subd.domain.com
* Duplicated default.settings.php and renamed the duplicate settings.php. Both files are in the directory
* Set directory permission to 755
* Set file permissions, variably, to 644, 666 and 777
