WordPress MU to Multisite HTACCESS

I would like to add something to my earlier article How to enable WordPress Multisite 3.0. If you are upgrading from WordPress MU (WPMU) to WordPress 3.0.x Multisite make sure to check your HTACCESS file. There have been many reports of broken images on Multisite installations after upgrading from WordPress MU. If you notice any broken images on your Multisite subdomains after upgrading, make sure to check your HTACCESS.

I tried the following HTACCESS and it fixed all these problems with broken or missing images:

#Wordpress Multi site
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
 
# uploaded files
RewriteRule ^files/(.+) wp-includes/ms-files.php?file=$1 [L]
 
RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^ - [L]
RewriteRule . index.php [L]
#END WordPress Multi Site

If you are using The Donncha Domain mapping plugin to allow users to use domain names, make sure to update to the latest version that is compatible with WordPress 3.0.x. Otherwise you could see this message when a blog user tries to login:

“You don’t have permission to view this site. Please contact the system administrator.”

To update to the latest version of Donncha’s domain mapping plugin:

WordPress 3.0 Domain Mapping 0.5.2

If you notice any other issues after updating to WordPress Multisite, let me know and I will see if there is any fix.

  1. What is the advantage of WordPress Multisite instead of just a number of installs. I have unlimited bandwidth and space. Would it make sense for me?

    • Hello Doug! One of the advantages I can see from my experience, is that you can manage many blogs from the same backend. If you have a testing domain or site, I would install Multisite there and play with it. See if you feel confortable with it or not. Also Multisite is used in many news sites or University community sites to offer users or students the chance to build their own blog.

  2. Another thing I found it this solved was GoDaddy and WordPress have some issues and this solved the Permalink name problem… go figure. Is it possible on your Director Hollywood theme blog to remove the sidebar for one page?

    • Hello Doug, I tried to contact you via email some days ago, did you get the email? If not, please contact me here: webmaster (at) wpthemesplanet.com Thanks.

  3. Hello, Love your theme, but want to customize it by giving it a header that better suites my needs. Possible? I use WordPress and am not very used to it yet. Any suggestions! Thanks for a great theme!

    • Hello Chris, very nice header you have there! I would also recommend to replace or remove the nav-bar background. You can simply open the style.css from Appearance -> editor and remvoe it from there or just reaplace with your own bar2.jpg image. If you need more help, contact me here: webmaster (at) wpthemesplanet.com Thanks, Alex.

  4. *whew* Thank GOD that I found this posting. I had this problem (after migrating from WP on Windows to Linux on GoDaddy) and I couldn’t figure out how to resolve this problem. Your .htaccess code worked beautifully. Thank you.

  5. Thank You! Worked on my WP-MS network of sites as well. Glad you posted this and was easily found with a google search
