I just ran the auto update to verion 3.9 today, but am having problems with the "Network Update".

I seem to have a firewall or network problem with this error :

Your server may not be able to connect to sites running on it. Error message: couldn't connect to host

Anyways, is there a way to run the database updates per blog ? Can I use a special URL ? Can I do it from shell command line ?

On an old forum post, someone suggested that update.php runs automatically the first time you log into your blog admin ( even if Network Update hasn't been run ). I wonder if that's true.

WP CLI has a command that can upgrade the database:

wp core update-db

If that command doesn't upgrade the entire network, you can pass in the site you want upgraded as an additional parameter


wp core update-db --site="http://example.com/testsite/"

You can get WP CLI from here:


it's also available on github

You can install using:

curl -L https://raw.github.com/wp-cli/builds/gh-pages/phar/wp-cli.phar > wp-cli.phar

It also comes with VVV

    Excellent suggestion. I installed wp-cli and wrote a shell script to update all 300 blogs. It worked great. Thanks
