For those new to WordPress MU you might like to check out Installing mu-plugins section in our comprehensive WordPress MU Manual and then follow the instructions below.

 

Here are the detailed step-by-step instructions:

 

1. Place the following files in the specified directories 2. Download your .htacess file onto your hard drive 3. Open up your .htacess file using EditPlus and add the following to your .htaccess under the line that handles uploaded files:

RewriteRule ^(.*/)?avatar/(.*) wp-content/avatar.php?file=$2 [L] 4. Save your .htaccess file. Upload your amended .htaccess file to your public_html folder and overwrite your existing file

 

TIP:

 

Check to confirm that the .htaccess file has been overwritten by making sure the last modified date is the same as the file you’ve uploaded. Some FTP clients have a hard time overwriting the .htaccess file and/or some servers are configured to not all the FTP client to overwrite the .htaccess file. If this happens you need to delete the file from the server and then upload the modified file. 5.

Set the file permission to 777 and click OK. 8. Create user directories inside the avatar directory 9. Right click on user directory, select file permissions, set the file permission to 777 and click OK 10. Repeat steps to create a blog directory inside the avatar directory. Then right click on blog directory, select file permissions, set the file permission to 777 and click OK 11. Log into your WPMU and test plugin is working by uploading an avatar to your profile.

  2. Did you add the following text to the correct location in the .htaccess file?
    3. RewriteRule ^(.*/)?avatar/(.*) wp-content/avatar.php?file=$2 [L]
  3. Did the .htaccess file get overwritten?
  4. Were the user and blog directories created properly? Are they inside the avatars directory in wp-content?
  5. Have the file permission for the avatar, user and blog directories been changed to 777?
