WordPress MU

all posts&pages are not found in the single posts & pages for all blogs but those come in index.how must fix this problem?
for example:
index: http://www.iranianmusic.webloghaa.com

post: http://iranianmusic.webloghaa.com/1388/12/08/pop-shokalbum-farzadfarzin/

or in my mu homepage :www.webloghaa.com
example post http://www.webloghaa.com/persian

it looks like your host not enabled the mod_rewrite module for your apache installation. ask them about it....

this is enable!

i think that eror is from .htaccess file. my permalink was Day and name and now i change it to default. now i can see posts for example http://webloghaa.com/?p=130 and not work in pages like: http://webloghaa.com/persian

there is this eror in all blogs
my .htaccess is:

RewriteEngine On
RewriteBase /

# Rewrite http://www.domain.com to domain.com
RewriteCond %{HTTP_HOST} ^www\.(.*)
RewriteRule ^(.*) http://%1/$1 [R,L]

#uploaded files
RewriteRule ^(.*/)?files/$ index.php [L]
RewriteRule ^(.*/)?files/(.*) wp-content/blogs.php?file=$2 [L]

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]

please explain for fix this problem. thanks again

You need

AllowOverride FileInfo Options

in the vhost entry for that webaccount so mod_rewrite will actually *read* the htaccess file. That's what's wrong.

I'm confuse now can u explain what i must do?

Explain more

Do you manage the server yourself, or do you have a support team you can contact?

i have support team

Then ask them or point them to this thread.

ok thanks
