WordPress MU

I have a blog site running.

desiblogs.co.uk

It has been running perfectly until now.

At the moment it redirects to one blog site (I don't know why)

For example.

http://desiblogs.co.uk goes to http://u3.desiblogs.co.uk

The same with all other blogs.

http://desiblogs.co.uk/news goes to the regular blog site, this same method works with the other blogs.

It's just the problem when the user goes to the blog through its root url.

I need urgent attention and help with this.

Thanks

Now suddenly goes to:

http://xhyzc.desiblogs.co.uk (Blog url doesn't exist)

check your apache config files, check your htaccess, check your error logs. Something changed on the server, stuff doesn't just do this by itself.

Checked with the apache files, they are alright

This is my .htaccess file:

RewriteEngine On
RewriteBase /

RewriteRule ^sitemap.xml /wp-content/blogs.php?file=sitemap.xml [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]

And my index.php file seems not to have any redirects inside it, neither does wp_blog_header.php

I have seen that you made a new installation ?

As far as I saw everything was working ok here with your old site... no cache involved somewhere ?

Yes i have reinstalled onto a test database and changed the config to my old database, then just added the themes and plugins used and now it works :D

I advise you to dig more into your system looking to your services you provide.

This because your problem was "EXTREMELY Urgent" it won't say you will be helped in your SLA time on your services.

I'm glad andrea was so kind to help you out that fast, but I think you need some other kind of support in such enviroments.

And I have to be honest, the things I suggested were standard sys/web admin procedures for when something breaks.

I know I just panicked and I couldn't find a problem in any file, I still don't know what the problem could be but I had to get rid of all my modded files and start again.

Lucky I took a full Backup :p

Thanks andrea_r for your help

Systems all working fine now.
