[Bugfix] Fix WordPress Multisite wrong blog titles and URLs

You may occasionally come across the case that changing the blog title and/or URLs of your multisite websites does not become effective.

The most obvious reason for this is a broken WordPress Multisite configuration. Make sure that you have configured your wp-config.php and your .htaccess files as specified under Settings > Network Setup within the Network Admin of your Multisite.

If everything is correctly set up, the next step would be to disable all plugins and check if this helps.

If the error still persists, there is another place where the bug may sit:

  1. Navigate to the filesystem of your website.
  2. Check if there are any files under wp-content/mu-plugins.
  3. Create a copy of all those files in a safe place (outside of your WordPress installation).
  4. Delete one after the other of these files and find out which one causes the bug.

Hint: If there is a file memcache-fix.php the chance is high that this file causes the trouble.
