WordPress MU

I have tried every solution in these forums and am still getting 404 errors after users try to post a comment in any blog. They go to subdomain.autiblogger.com/wp-comments-post.php. Domain is autiblogger.com.

This problem has just started after moving the site from dreamhost to a VPS on liquid web.

Here's my .htaccess file:

RewriteEngine On
RewriteBase /

RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule . - [L]
RewriteRule ^([_0-9a-zA-Z-]+/)?(wp-.*) $2 [L]
RewriteRule ^([_0-9a-zA-Z-]+/)?(.*.php)$ $2 [L]
RewriteRule . index.php [L]

Here is the error from the server apache log:

xx.xxx.xxx.xxx - - [23/Sep/2006:10:51:08 -0700] "POST /wp-comments-post.php HTTP/1.1" 404 14095 "http://test.autiblogger.com/2006/08/26/long-link-test/" "Mozilla/5.0 (Macintosh; U; Intel Mac OS X; en-US; rv:1.8.0.7) Gecko/20060909 Firefox/1.5.0.7"

Any help is appreciated. Thanks!

Have you looked to see if wp-comments-post.php is there?

What permissions is it set to? Should be 644. Who is the file owned by? Should be either your account or the webserver.

Thanks drmike! Ordinarily I would feel dumb about not even checking if the file is there, but I am too happy to even care :) This is not the first file that has gone missing after the transfer from dreamhost. I often have problems when doing server to server transfers from there.
